+
+  For each key, if the key does not exist, it is created. If it already
+  exists and it was inherited from its constructor, the constructor's
+  key is cloned.

+// COMPUTED PROPERTY
+//
+
+/**
+  A computed property transforms an objects function into a property.
+
+  By default the function backing the computed property will only be called
+  once and the result will be cached. You can specify various properties
+  that your computed property is dependent on. This will force the cached
+  result to be recomputed if the dependencies are modified.
+
+  In the following example we declare a computed property (by calling
+  `.property()` on the fullName function) and setup the properties
+  dependencies (depending on firstName and lastName). The fullName function
+  will be called once (regardless of how many times it is accessed) as long
+  as it's dependencies have not been changed. Once firstName or lastName are updated
+  any future calls (or anything bound) to fullName will incorporate the new
+  values.
+
+  ```javascript
+  Person = Ember.Object.extend({
+    // these will be supplied by `create`
+    firstName: null,
+    lastName: null,
+
+    fullName: function() {
+      var firstName = this.get('firstName');
+      var lastName = this.get('lastName');
+
+     return firstName + ' ' + lastName;
+    }.property('firstName', 'lastName')
+  });
+
+  var tom = Person.create({
+    firstName: "Tom",
+    lastName: "Dale"
+  });
+
+  tom.get('fullName') // "Tom Dale"
+  ```
+
+  You can also define what Ember should do when setting a computed property.
+  If you try to set a computed property, it will be invoked with the key and
+  value you want to set it to. You can also accept the previous value as the
+  third parameter.
+
+  ```javascript
+
+ Person = Ember.Object.extend({
+    // these will be supplied by `create`
+    firstName: null,
+    lastName: null,
+
+    fullName: function(key, value, oldValue) {
+      // getter
+      if (arguments.length === 1) {
+        var firstName = this.get('firstName');
+        var lastName = this.get('lastName');
+
+        return firstName + ' ' + lastName;
+
+      // setter
+      } else {
+        var name = value.split(" ");
+
+        this.set('firstName', name[0]);
+        this.set('lastName', name[1]);
+
+        return value;
+      }
+    }.property('firstName', 'lastName')
+  });
+
+  var person = Person.create();
+  person.set('fullName', "Peter Wagenet");
+  person.get('firstName') // Peter
+  person.get('lastName') // Wagenet

+

+  scheduled by `Ember.run.later` that expire right around the same
+  time that `Ember.run.next` operations will fire.
+
+  Note that there are often alternatives to using `Ember.run.next`.
+  For instance, if you'd like to schedule an operation to happen
+  after all DOM element operations have completed within the current
+  run loop, you can make use of the `afterRender` run loop queue (added
+  by the `ember-views` package, along with the preceding `render` queue
+  where all the DOM element operations happen). Example:
+
+  ```javascript
+  App.MyCollectionView = Ember.CollectionView.extend({
+    didInsertElement: function() {
+      Ember.run.scheduleOnce('afterRender', this, 'processChildElements');
+    },
+    processChildElements: function() {
+      // ... do something with collectionView's child view
+      // elements after they've finished rendering, which
+      // can't be done within the CollectionView's
+      // `didInsertElement` hook because that gets run
+      // before the child elements have been added to the DOM.
+    }
+  });
+  ```
+
+  One benefit of the above approach compared to using `Ember.run.next` is
+  that you will be able to perform DOM/CSS operations before unprocessed
+  elements are rendered to the screen, which may prevent flickering or
+  other artifacts caused by delaying processing until after rendering.
+
+  The other major benefit to the above approach is that `Ember.run.next`
+  introduces an element of non-determinism, which can make things much
+  harder to test, due to its reliance on `setTimeout`; it's much harder
+  to guarantee the order of scheduled operations when they are scheduled
+  outside of the current run loop, i.e. with `Ember.run.next`.

+/**
+  An `Ember.Binding` connects the properties of two objects so that whenever
+  the value of one property changes, the other property will be changed also.
+
+  ## Automatic Creation of Bindings with `/^*Binding/`-named Properties
+
+  You do not usually create Binding objects directly but instead describe
+  bindings in your class or object definition using automatic binding
+  detection.
+
+  Properties ending in a `Binding` suffix will be converted to `Ember.Binding`
+  instances. The value of this property should be a string representing a path
+  to another object or a custom binding instanced created using Binding helpers
+  (see "One Way Bindings"):
+
+  ```
+  valueBinding: "MyApp.someController.title"
+  ```
+
+  This will create a binding from `MyApp.someController.title` to the `value`
+  property of your object instance automatically. Now the two values will be
+  kept in sync.
+
+  ## One Way Bindings
+
+  One especially useful binding customization you can use is the `oneWay()`
+  helper. This helper tells Ember that you are only interested in
+  receiving changes on the object you are binding from. For example, if you
+  are binding to a preference and you want to be notified if the preference
+  has changed, but your object will not be changing the preference itself, you
+  could do:
+
+  ```
+  bigTitlesBinding: Ember.Binding.oneWay("MyApp.preferencesController.bigTitles")
+  ```
+
+  This way if the value of `MyApp.preferencesController.bigTitles` changes the
+  `bigTitles` property of your object will change also. However, if you
+  change the value of your `bigTitles` property, it will not update the
+  `preferencesController`.
+
+  One way bindings are almost twice as fast to setup and twice as fast to
+  execute because the binding only has to worry about changes to one side.
+
+  You should consider using one way bindings anytime you have an object that
+  may be created frequently and you do not intend to change a property; only
+  to monitor it for changes (such as in the example above).
+
+  ## Adding Bindings Manually
+
+  All of the examples above show you how to configure a custom binding, but the
+  result of these customizations will be a binding template, not a fully active
+  Binding instance. The binding will actually become active only when you
+  instantiate the object the binding belongs to. It is useful however, to
+  understand what actually happens when the binding is activated.
+
+  For a binding to function it must have at least a `from` property and a `to`
+  property. The `from` property path points to the object/key that you want to
+  bind from while the `to` path points to the object/key you want to bind to.
+
+  When you define a custom binding, you are usually describing the property
+  you want to bind from (such as `MyApp.someController.value` in the examples
+  above). When your object is created, it will automatically assign the value
+  you want to bind `to` based on the name of your binding key. In the
+  examples above, during init, Ember objects will effectively call
+  something like this on your binding:
+
+  ```javascript
+  binding = Ember.Binding.from(this.valueBinding).to("value");
+  ```
+
+  This creates a new binding instance based on the template you provide, and
+  sets the to path to the `value` property of the new object. Now that the
+  binding is fully configured with a `from` and a `to`, it simply needs to be
+  connected to become active. This is done through the `connect()` method:
+
+  ```javascript
+  binding.connect(this);
+  ```
+
+  Note that when you connect a binding you pass the object you want it to be
+  connected to. This object will be used as the root for both the from and
+  to side of the binding when inspecting relative paths. This allows the
+  binding to be automatically inherited by subclassed objects as well.
+
+  Now that the binding is connected, it will observe both the from and to side
+  and relay changes.
+
+  If you ever needed to do so (you almost never will, but it is useful to
+  understand this anyway), you could manually create an active binding by
+  using the `Ember.bind()` helper method. (This is the same method used by
+  to setup your bindings on objects):
+
+  ```javascript
+  Ember.bind(MyApp.anotherObject, "value", "MyApp.someController.value");
+  ```
+
+  Both of these code fragments have the same effect as doing the most friendly
+  form of binding creation like so:
+
+  ```javascript
+  MyApp.anotherObject = Ember.Object.create({
+    valueBinding: "MyApp.someController.value",
+
+    // OTHER CODE FOR THIS OBJECT...
+  });
+  ```
+
+  Ember's built in binding creation method makes it easy to automatically
+  create bindings for you. You should always use the highest-level APIs
+  available, even if you understand how it works underneath.

+
+      `RSVP.filter` will also wait for any promises returned from `filterFn`.

+     `RSVP.map` is similar to JavaScript's native `map` method, except that it
+      waits for all promises to become fulfilled before running the `mapFn` on
+      each item in given to `promises`. `RSVP.map` returns a promise that will
+      become fulfilled with the result of running `mapFn` on the values the promises
+      become fulfilled with.
+
+      For example:
+
+      ```javascript
+
+      var promise1 = RSVP.resolve(1);
+      var promise2 = RSVP.resolve(2);
+      var promise3 = RSVP.resolve(3);
+      var promises = [ promise1, promise2, promise3 ];
+
+      var mapFn = function(item){
+        return item + 1;
+      };
+
+      RSVP.map(promises, mapFn).then(function(result){
+        // result is [ 2, 3, 4 ]
+      });
+      ```
+
+      If any of the `promises` given to `RSVP.map` are rejected, the first promise
+      that is rejected will be given as an argument to the returned promise's
+      rejection handler. For example:
+
+      ```javascript
+      var promise1 = RSVP.resolve(1);
+      var promise2 = RSVP.reject(new Error("2"));
+      var promise3 = RSVP.reject(new Error("3"));
+      var promises = [ promise1, promise2, promise3 ];
+
+      var mapFn = function(item){
+        return item + 1;
+      };
+
+      RSVP.map(promises, mapFn).then(function(array){
+        // Code here never runs because there are rejected promises!
+      }, function(reason) {
+        // reason.message === "2"
+      });
+      ```
+
+      `RSVP.map` will also wait if a promise is returned from `mapFn`. For example,
+      say you want to get all comments from a set of blog posts, but you need
+      the blog posts first becuase they contain a url to those comments.
+
+      ```javscript
+
+      var mapFn = function(blogPost){
+        // getComments does some ajax and returns an RSVP.Promise that is fulfilled
+        // with some comments data
+        return getComments(blogPost.comments_url);
+      };
+
+      // getBlogPosts does some ajax and returns an RSVP.Promise that is fulfilled
+      // with some blog post data
+      RSVP.map(getBlogPosts(), mapFn).then(function(comments){
+        // comments is the result of asking the server for the comments
+        // of all blog posts returned from getBlogPosts()
+      });
+      ```

+      `RSVP.denodeify` takes a "node-style" function and returns a function that
+      will return an `RSVP.Promise`. You can use `denodeify` in Node.js or the
+      browser when you'd prefer to use promises over using callbacks. For example,
+      `denodeify` transforms the following:
+
+      ```javascript
+      var fs = require('fs');
+
+      fs.readFile('myfile.txt', function(err, data){
+        if (err) return handleError(err);
+        handleData(data);
+      });
+      ```
+
+      into:
+
+      ```javascript
+      var fs = require('fs');
+
+      var readFile = RSVP.denodeify(fs.readFile);
+
+      readFile('myfile.txt').then(handleData, handleError);
+      ```
+
+      Using `denodeify` makes it easier to compose asynchronous operations instead
+      of using callbacks. For example, instead of:
+
+      ```javascript
+      var fs = require('fs');
+      var log = require('some-async-logger');
+
+      fs.readFile('myfile.txt', function(err, data){
+        if (err) return handleError(err);
+        fs.writeFile('myfile2.txt', data, function(err){
+          if (err) throw err;
+          log('success', function(err) {
+            if (err) throw err;
+          });
+        });
+      });
+      ```
+
+      You can chain the operations together using `then` from the returned promise:
+
+      ```javascript
+      var fs = require('fs');
+      var denodeify = RSVP.denodeify;
+      var readFile = denodeify(fs.readFile);
+      var writeFile = denodeify(fs.writeFile);
+      var log = denodeify(require('some-async-logger'));
+
+      readFile('myfile.txt').then(function(data){
+        return writeFile('myfile2.txt', data);
+      }).then(function(){
+        return log('SUCCESS');
+      }).then(function(){
+        // success handler

+      Promise objects represent the eventual result of an asynchronous operation. The
+      primary way of interacting with a promise is through its `then` method, which
+      registers callbacks to receive either a promise’s eventual value or the reason
+      why the promise cannot be fulfilled.
+
+      Terminology
+      -----------
+
+      - `promise` is an object or function with a `then` method whose behavior conforms to this specification.
+      - `thenable` is an object or function that defines a `then` method.
+      - `value` is any legal JavaScript value (including undefined, a thenable, or a promise).
+      - `exception` is a value that is thrown using the throw statement.
+      - `reason` is a value that indicates why a promise was rejected.
+      - `settled` the final resting state of a promise, fulfilled or rejected.
+
+      A promise can be in one of three states: pending, fulfilled, or rejected.
+
+      Promises that are fulfilled have a fulfillment value and are in the fulfilled
+      state.  Promises that are rejected have a rejection reason and are in the
+      rejected state.  A fulfillment value is never a thenable.  Similarly, a
+      rejection reason is never a thenable.
+
+      Promises can also be said to *resolve* a value.  If this value is also a
+      promise, then the original promise's settled state will match the value's
+      settled state.  So a promise that *resolves* a promise that rejects will
+      itself reject, and a promise that *resolves* a promise that fulfills will
+      itself fulfill.
+
+
+      Basic Usage:
+      ------------
+
+      ```js
+      var promise = new Promise(function(resolve, reject) {
+        // on success
+        resolve(value);
+
+        // on failure
+        reject(reason);
+      });
+
+      promise.then(function(value) {
+        // on fulfillment
+      }, function(reason) {
+        // on rejection
+      });
+      ```
+
+      Advanced Usage:
+      ---------------
+
+      Promises shine when abstracting away asynchronous interactions such as
+      `XMLHttpRequest`s.
+
+      ```js
+      function getJSON(url) {
+        return new Promise(function(resolve, reject){
+          var xhr = new XMLHttpRequest();
+
+          xhr.open('GET', url);
+          xhr.onreadystatechange = handler;
+          xhr.responseType = 'json';
+          xhr.setRequestHeader('Accept', 'application/json');
+          xhr.send();
+
+          function handler() {
+            if (this.readyState === this.DONE) {
+              if (this.status === 200) {
+                resolve(this.response);
+              } else {
+                reject(new Error("getJSON: `" + url + "` failed with status: [" + this.status + "]");
+              }
+            }
+          };
+        });
+      }
+
+      getJSON('/posts.json').then(function(json) {
+        // on fulfillment
+      }, function(reason) {
+        // on rejection
+      });
+      ```
+
+      Unlike callbacks, promises are great composable primitives.
+
+      ```js
+      Promise.all([
+        getJSON('/posts'),
+        getJSON('/comments')
+      ]).then(function(values){
+        values[0] // => postsJSON
+        values[1] // => commentsJSON
+
+        return values;
+      });
+      ```

+        // If `findUser` rejected, `reason` will be "`findUser` rejected and we're unhappy".
+      });
+      ```
+      If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.
+
+      ```js
+      findUser().then(function (user) {
+        throw new PedagogicalException("Upstream error");
+      }).then(function (value) {
+        // never reached
+      }).then(function (value) {
+        // never reached
+      }, function (reason) {
+        // The `PedgagocialException` is propagated all the way down to here
+      });
+      ```
+
+      Assimilation
+      ------------
+
+      Sometimes the value you want to propagate to a downstream promise can only be
+      retrieved asynchronously. This can be achieved by returning a promise in the
+      fulfillment or rejection handler. The downstream promise will then be pending
+      until the returned promise is settled. This is called *assimilation*.
+
+      ```js
+      findUser().then(function (user) {
+        return findCommentsByAuthor(user);
+      }).then(function (comments) {
+        // The user's comments are now available
+      });
+      ```
+
+      If the assimliated promise rejects, then the downstream promise will also reject.
+
+      ```js
+      findUser().then(function (user) {
+        return findCommentsByAuthor(user);
+      }).then(function (comments) {
+        // If `findCommentsByAuthor` fulfills, we'll have the value here
+      }, function (reason) {
+        // If `findCommentsByAuthor` rejects, we'll have the reason here
+      });
+      ```

+      ```
+
+      In the case of a non-promise, a promise which will fulfill with that value is

+      have something that could either be a promise or a value. RSVP.resolve
+      will have the same effect but will create a new promise wrapper if the
+      argument is a promise.
+      * `RSVP.Promise.cast` is a way of casting incoming thenables or promise subclasses to
+      promises of the exact class specified, so that the resulting object's `then` is
+      ensured to have the behavior of the constructor you are calling cast on (i.e., RSVP.Promise).

+      promise will become rejected:

+
+      Promises A+ specifies that any exceptions that occur with a promise must be
+      caught by the promises implementation and bubbled to the last handler. For
+      this reason, it is recommended that you always specify a second rejection

+      outside of the promise, so it bubbles up to your console if in the browser,
+      or domain/cause uncaught exception in Node. `rethrow` will also throw the
+      error again so the error can be handled by the promise per the spec.
+
+      ```javascript
+      function throws(){
+        throw new Error('Whoops!');

+
+      The 'Whoops' error will be thrown on the next turn of the event loop

+  features of the Ember object model.
+
+  Properties and observers allow one object to observe changes to a
+  property on another object. This is one of the fundamental ways that
+  models, controllers and views communicate with each other in an Ember
+  application.
+
+  Any object that has this mixin applied can be used in observer
+  operations. That includes `Ember.Object` and most objects you will
+  interact with as you write your Ember application.
+
+  Note that you will not generally apply this mixin to classes yourself,
+  but you will use the features provided by this module frequently, so it
+  is important to understand how to use it.
+
+  ## Using `get()` and `set()`
+
+  Because of Ember's support for bindings and observers, you will always
+  access properties using the get method, and set properties using the
+  set method. This allows the observing objects to be notified and
+  computed properties to be handled properly.
+
+  More documentation about `get` and `set` are below.
+
+  ## Observing Property Changes
+
+  You typically observe property changes simply by adding the `observes`
+  call to the end of your method declarations in classes that you write.
+  For example:
+
+  ```javascript
+  Ember.Object.extend({
+    valueObserver: function() {
+      // Executes whenever the "value" property changes
+    }.observes('value')
+  });
+  ```
+
+  Although this is the most common way to add an observer, this capability
+  is actually built into the `Ember.Object` class on top of two methods
+  defined in this mixin: `addObserver` and `removeObserver`. You can use
+  these two methods to add and remove observers yourself if you need to
+  do so at runtime.
+
+  To add an observer for a property, call:
+
+  ```javascript
+  object.addObserver('propertyKey', targetObject, targetAction)
+  ```
+
+  This will call the `targetAction` method on the `targetObject` whenever
+  the value of the `propertyKey` changes.
+
+  Note that if `propertyKey` is a computed property, the observer will be
+  called when any of the property dependencies are changed, even if the
+  resulting value of the computed property is unchanged. This is necessary
+  because computed properties are not computed until `get` is called.
+
+  @class Observable
+  @namespace Ember
+*/
+Ember.Observable = Ember.Mixin.create({
+
+  /**
+    Retrieves the value of a property from the object.
+
+    This method is usually similar to using `object[keyName]` or `object.keyName`,
+    however it supports both computed properties and the unknownProperty
+    handler.
+
+    Because `get` unifies the syntax for accessing all these kinds
+    of properties, it can make many refactorings easier, such as replacing a
+    simple property with a computed property, or vice versa.
+
+    ### Computed Properties
+
+    Computed properties are methods defined with the `property` modifier
+    declared at the end, such as:
+
+    ```javascript
+    fullName: function() {
+      return this.get('firstName') + ' ' + this.get('lastName');
+    }.property('firstName', 'lastName')
+    ```
+
+    When you call `get` on a computed property, the function will be
+    called and the return value will be returned instead of the function
+    itself.
+
+    ### Unknown Properties
+
+    Likewise, if you try to call `get` on a property whose value is
+    `undefined`, the `unknownProperty()` method will be called on the object.
+    If this method returns any value other than `undefined`, it will be returned
+    instead. This allows you to implement "virtual" properties that are
+    not defined upfront.
+
+    @method get
+    @param {String} keyName The property to retrieve
+    @return {Object} The property value or undefined.
+  */
+  get: function(keyName) {
+    return get(this, keyName);
+  },
+
+  /**
+    To get multiple properties at once, call `getProperties`
+    with a list of strings or an array:
+
+    ```javascript
+    record.getProperties('firstName', 'lastName', 'zipCode');  // { firstName: 'John', lastName: 'Doe', zipCode: '10011' }
+    ```
+
+    is equivalent to:
+
+    ```javascript
+    record.getProperties(['firstName', 'lastName', 'zipCode']);  // { firstName: 'John', lastName: 'Doe', zipCode: '10011' }
+    ```
+
+    @method getProperties
+    @param {String...|Array} list of keys to get
+    @return {Hash}
+  */
+  getProperties: function() {
+    return getProperties.apply(null, [this].concat(slice.call(arguments)));
+  },
+
+  /**
+    Sets the provided key or path to the value.
+
+    This method is generally very similar to calling `object[key] = value` or
+    `object.key = value`, except that it provides support for computed
+    properties, the `setUnknownProperty()` method and property observers.
+
+    ### Computed Properties
+
+    If you try to set a value on a key that has a computed property handler
+    defined (see the `get()` method for an example), then `set()` will call
+    that method, passing both the value and key instead of simply changing
+    the value itself. This is useful for those times when you need to
+    implement a property that is composed of one or more member
+    properties.
+
+    ### Unknown Properties
+
+    If you try to set a value on a key that is undefined in the target
+    object, then the `setUnknownProperty()` handler will be called instead. This
+    gives you an opportunity to implement complex "virtual" properties that
+    are not predefined on the object. If `setUnknownProperty()` returns
+    undefined, then `set()` will simply set the value on the object.
+
+    ### Property Observers
+
+    In addition to changing the property, `set()` will also register a property
+    change with the object. Unless you have placed this call inside of a
+    `beginPropertyChanges()` and `endPropertyChanges(),` any "local" observers
+    (i.e. observer methods declared on the same object), will be called
+    immediately. Any "remote" observers (i.e. observer methods declared on
+    another object) will be placed in a queue and called at a later time in a
+    coalesced manner.
+
+    ### Chaining
+
+    In addition to property changes, `set()` returns the value of the object
+    itself so you can do chaining like this:
+
+    ```javascript
+    record.set('firstName', 'Charles').set('lastName', 'Jolley');
+    ```
+
+    @method set
+    @param {String} keyName The property to set
+    @param {Object} value The value to set or `null`.
+    @return {Ember.Observable}
+  */
+  set: function(keyName, value) {
+    set(this, keyName, value);
+    return this;
+  },
+
+
+  /**
+    Sets a list of properties at once. These properties are set inside
+    a single `beginPropertyChanges` and `endPropertyChanges` batch, so
+    observers will be buffered.
+
+    ```javascript
+    record.setProperties({ firstName: 'Charles', lastName: 'Jolley' });
+    ```
+
+    @method setProperties
+    @param {Hash} hash the hash of keys and values to set
+    @return {Ember.Observable}
+  */
+  setProperties: function(hash) {
+    return Ember.setProperties(this, hash);
+  },

+  /**
+    Adds an observer on a property.
+
+    This is the core method used to register an observer for a property.
+
+    Once you call this method, any time the key's value is set, your observer
+    will be notified. Note that the observers are triggered any time the
+    value is set, regardless of whether it has actually changed. Your
+    observer should be prepared to handle that.
+
+    You can also pass an optional context parameter to this method. The
+    context will be passed to your observer method whenever it is triggered.
+    Note that if you add the same target/method pair on a key multiple times
+    with different context parameters, your observer will only be called once
+    with the last context you passed.
+
+    ### Observer Methods
+
+    Observer methods you pass should generally have the following signature if
+    you do not pass a `context` parameter:
+
+    ```javascript
+    fooDidChange: function(sender, key, value, rev) { };
+    ```
+
+    The sender is the object that changed. The key is the property that
+    changes. The value property is currently reserved and unused. The rev
+    is the last property revision of the object when it changed, which you can
+    use to detect if the key value has really changed or not.
+
+    If you pass a `context` parameter, the context will be passed before the
+    revision like so:
+
+    ```javascript
+    fooDidChange: function(sender, key, value, context, rev) { };
+    ```
+
+    Usually you will not need the value, context or revision parameters at
+    the end. In this case, it is common to write observer methods that take
+    only a sender and key value as parameters or, if you aren't interested in
+    any of these values, to write an observer that has no parameters at all.
+
+    @method addObserver
+    @param {String} key The key to observer
+    @param {Object} target The target object to invoke
+    @param {String|Function} method The method to invoke.

+
+    NOTE: If you do override `init` for a framework class like `Ember.View` or
+    `Ember.ArrayController`, be sure to call `this._super()` in your
+    `init` declaration! If you don't, Ember may not have an opportunity to
+    do important setup work, and you'll see strange behavior in your
+    application.
+
+    @method init

+  init: function() {},
+
+  /**
+    Defines the properties that will be concatenated from the superclass
+    (instead of overridden).
+
+    By default, when you extend an Ember class a property defined in
+    the subclass overrides a property with the same name that is defined
+    in the superclass. However, there are some cases where it is preferable
+    to build up a property's value by combining the superclass' property
+    value with the subclass' value. An example of this in use within Ember
+    is the `classNames` property of `Ember.View`.
+
+    Here is some sample code showing the difference between a concatenated
+    property and a normal one:
+
+    ```javascript
+    App.BarView = Ember.View.extend({
+      someNonConcatenatedProperty: ['bar'],
+      classNames: ['bar']
+    });
+
+    App.FooBarView = App.BarView.extend({
+      someNonConcatenatedProperty: ['foo'],
+      classNames: ['foo'],
+    });
+
+    var fooBarView = App.FooBarView.create();
+    fooBarView.get('someNonConcatenatedProperty'); // ['foo']
+    fooBarView.get('classNames'); // ['ember-view', 'bar', 'foo']
+    ```
+
+    This behavior extends to object creation as well. Continuing the
+    above example:
+
+    ```javascript
+    var view = App.FooBarView.create({
+      someNonConcatenatedProperty: ['baz'],
+      classNames: ['baz']
+    })
+    view.get('someNonConcatenatedProperty'); // ['baz']
+    view.get('classNames'); // ['ember-view', 'bar', 'foo', 'baz']
+    ```
+    Adding a single property that is not an array will just add it in the array:
+
+    ```javascript
+    var view = App.FooBarView.create({
+      classNames: 'baz'
+    })
+    view.get('classNames'); // ['ember-view', 'bar', 'foo', 'baz']
+    ```
+
+    Using the `concatenatedProperties` property, we can tell to Ember that mix
+    the content of the properties.
+
+    In `Ember.View` the `classNameBindings` and `attributeBindings` properties
+    are also concatenated, in addition to `classNames`.
+
+    This feature is available for you to use throughout the Ember object model,
+    although typical app developers are likely to use it infrequently. Since
+    it changes expectations about behavior of properties, you should properly
+    document its usage in each individual concatenated property (to not
+    mislead your users to think they can override the property in a subclass).

+        alert(thing);
+       }
+    });
+    ```
+
+    This defines a new subclass of Ember.Object: `App.Person`. It contains one method: `say()`.
+
+    You can also create a subclass from any existing class by calling its `extend()`  method. For example, you might want to create a subclass of Ember's built-in `Ember.View` class:
+
+    ```javascript
+    App.PersonView = Ember.View.extend({
+      tagName: 'li',
+      classNameBindings: ['isAdministrator']
+    });
+    ```
+
+    When defining a subclass, you can override methods but still access the implementation of your parent class by calling the special `_super()` method:
+
+    ```javascript
+    App.Person = Ember.Object.extend({
+      say: function(thing) {
+        var name = this.get('name');
+        alert(name + ' says: ' + thing);
+      }
+    });
+
+    App.Soldier = App.Person.extend({
+      say: function(thing) {
+        this._super(thing + ", sir!");
+      },
+      march: function(numberOfHours) {
+        alert(this.get('name') + ' marches for ' + numberOfHours + ' hours.')
+      }
+    });
+
+    var yehuda = App.Soldier.create({
+      name: "Yehuda Katz"
+    });
+
+    yehuda.say("Yes");  // alerts "Yehuda Katz says: Yes, sir!"
+    ```
+
+    The `create()` on line #17 creates an *instance* of the `App.Soldier` class. The `extend()` on line #8 creates a *subclass* of `App.Person`. Any instance of the `App.Person` class will *not* have the `march()` method.
+
+    You can also pass `Ember.Mixin` classes to add additional properties to the subclass.
+
+    ```javascript
+    App.Person = Ember.Object.extend({
+      say: function(thing) {
+        alert(this.get('name') + ' says: ' + thing);
+      }
+    });
+
+    App.SingingMixin = Ember.Mixin.create({
+      sing: function(thing){
+        alert(this.get('name') + ' sings: la la la ' + thing);
+      }
+    });
+
+    App.BroadwayStar = App.Person.extend(App.SingingMixin, {
+      dance: function() {
+        alert(this.get('name') + ' dances: tap tap tap tap ');
+      }
+    });
+    ```
+
+    The `App.BroadwayStar` class contains three methods: `say()`, `sing()`, and `dance()`.

+  This mixin defines the common interface implemented by enumerable objects
+  in Ember. Most of these methods follow the standard Array iteration
+  API defined up to JavaScript 1.8 (excluding language-specific features that
+  cannot be emulated in older versions of JavaScript).
+
+  This mixin is applied automatically to the Array class on page load, so you
+  can use any of these methods on simple arrays. If Array already implements
+  one of these methods, the mixin will not override them.
+
+  ## Writing Your Own Enumerable
+
+  To make your own custom class enumerable, you need two items:
+
+  1. You must have a length property. This property should change whenever
+     the number of items in your enumerable object changes. If you use this
+     with an `Ember.Object` subclass, you should be sure to change the length
+     property using `set().`
+
+  2. You must implement `nextObject().` See documentation.
+
+  Once you have these two methods implemented, apply the `Ember.Enumerable` mixin
+  to your class and you will be able to enumerate the contents of your object
+  like any other collection.
+
+  ## Using Ember Enumeration with Other Libraries
+
+  Many other libraries provide some kind of iterator or enumeration like
+  facility. This is often where the most common API conflicts occur.
+  Ember's API is designed to be as friendly as possible with other
+  libraries by implementing only methods that mostly correspond to the
+  JavaScript 1.8 API.
+
+  @class Enumerable
+  @namespace Ember

+    Implement this method to make your class enumerable.
+
+    This method will be call repeatedly during enumeration. The index value
+    will always begin with 0 and increment monotonically. You don't have to
+    rely on the index value to determine what object to return, but you should
+    always check the value and start from the beginning when you see the
+    requested index is 0.
+
+    The `previousObject` is the object that was returned from the last call
+    to `nextObject` for the current iteration. This is a useful way to
+    manage iteration if you are tracing a linked list, for example.
+
+    Finally the context parameter will always contain a hash you can use as
+    a "scratchpad" to maintain any other state you need in order to iterate
+    properly. The context object is reused and is not reset between
+    iterations so make sure you setup the context with a fresh state whenever
+    the index parameter is 0.
+
+    Generally iterators will continue to call `nextObject` until the index
+    reaches the your current length-1. If you run out of data before this
+    time for some reason, you should simply return undefined.
+
+    The default implementation of this method simply looks up the index.
+    This works great on any Array-like objects.

+/**
+  This mixin implements Observer-friendly Array-like behavior. It is not a
+  concrete implementation, but it can be used up by other classes that want
+  to appear like arrays.
+
+  For example, ArrayProxy and ArrayController are both concrete classes that can
+  be instantiated to implement array-like behavior. Both of these classes use
+  the Array Mixin by way of the MutableArray mixin, which allows observable
+  changes to be made to the underlying array.
+
+  Unlike `Ember.Enumerable,` this mixin defines methods specifically for
+  collections that provide index-ordered access to their contents. When you
+  are designing code that needs to accept any kind of Array-like object, you
+  should use these methods instead of Array primitives because these will
+  properly notify observers of changes to the array.
+
+  Although these methods are efficient, they do add a layer of indirection to
+  your application so it is a good idea to use them only when you need the
+  flexibility of using both true JavaScript arrays and "virtual" arrays such
+  as controllers and collections.
+
+  You can use the methods defined in this module to access and modify array
+  contents in a KVO-friendly way. You can also be notified whenever the
+  membership of an array changes by changing the syntax of the property to
+  `.observes('*myProperty.[]')`.
+
+  To support `Ember.Array` in your own class, you must override two
+  primitives to use it: `replace()` and `objectAt()`.
+
+  Note that the Ember.Array mixin also incorporates the `Ember.Enumerable`
+  mixin. All `Ember.Array`-like objects are also enumerable.

+/**
+  Creates a computed property which operates on dependent arrays and
+  is updated with "one at a time" semantics. When items are added or
+  removed from the dependent array(s) a reduce computed only operates
+  on the change instead of re-evaluating the entire array.
+
+  If there are more than one arguments the first arguments are
+  considered to be dependent property keys. The last argument is
+  required to be an options object. The options object can have the
+  following four properties:
+
+  `initialValue` - A value or function that will be used as the initial
+  value for the computed. If this property is a function the result of calling
+  the function will be used as the initial value. This property is required.
+
+  `initialize` - An optional initialize function. Typically this will be used
+  to set up state on the instanceMeta object.
+
+  `removedItem` - A function that is called each time an element is removed
+  from the array.
+
+  `addedItem` - A function that is called each time an element is added to
+  the array.
+
+
+  The `initialize` function has the following signature:
+
+  ```javascript
+   function (initialValue, changeMeta, instanceMeta)
+  ```
+
+  `initialValue` - The value of the `initialValue` property from the
+  options object.
+
+  `changeMeta` - An object which contains meta information about the
+  computed. It contains the following properties:
+
+     - `property` the computed property
+     - `propertyName` the name of the property on the object
+
+  `instanceMeta` - An object that can be used to store meta
+  information needed for calculating your computed. For example a
+  unique computed might use this to store the number of times a given
+  element is found in the dependent array.
+
+
+  The `removedItem` and `addedItem` functions both have the following signature:
+
+  ```javascript
+  function (accumulatedValue, item, changeMeta, instanceMeta)
+  ```
+
+  `accumulatedValue` - The value returned from the last time
+  `removedItem` or `addedItem` was called or `initialValue`.
+
+  `item` - the element added or removed from the array
+
+  `changeMeta` - An object which contains meta information about the
+  change. It contains the following properties:
+
+    - `property` the computed property
+    - `propertyName` the name of the property on the object
+    - `index` the index of the added or removed item
+    - `item` the added or removed item: this is exactly the same as
+      the second arg
+    - `arrayChanged` the array that triggered the change. Can be
+      useful when depending on multiple arrays.
+
+  For property changes triggered on an item property change (when
+  depKey is something like `someArray.@each.someProperty`),
+  `changeMeta` will also contain the following property:
+
+    - `previousValues` an object whose keys are the properties that changed on
+    the item, and whose values are the item's previous values.
+
+  `previousValues` is important Ember coalesces item property changes via
+  Ember.run.once. This means that by the time removedItem gets called, item has
+  the new values, but you may need the previous value (eg for sorting &
+  filtering).
+
+  `instanceMeta` - An object that can be used to store meta
+  information needed for calculating your computed. For example a
+  unique computed might use this to store the number of times a given
+  element is found in the dependent array.
+
+  The `removedItem` and `addedItem` functions should return the accumulated
+  value. It is acceptable to not return anything (ie return undefined)
+  to invalidate the computation. This is generally not a good idea for
+  arrayComputed but it's used in eg max and min.
+
+  Note that observers will be fired if either of these functions return a value
+  that differs from the accumulated value.  When returning an object that
+  mutates in response to array changes, for example an array that maps
+  everything from some other array (see `Ember.computed.map`), it is usually
+  important that the *same* array be returned to avoid accidentally triggering observers.
+
+  Example
+
+  ```javascript
+  Ember.computed.max = function (dependentKey) {
+    return Ember.reduceComputed(dependentKey, {
+      initialValue: -Infinity,
+
+      addedItem: function (accumulatedValue, item, changeMeta, instanceMeta) {
+        return Math.max(accumulatedValue, item);
+      },
+
+      removedItem: function (accumulatedValue, item, changeMeta, instanceMeta) {
+        if (item < accumulatedValue) {
+          return accumulatedValue;
+        }
+      }
+    });
+  };
+  ```
+
+  Dependent keys may refer to `@this` to observe changes to the object itself,
+  which must be array-like, rather than a property of the object.  This is
+  mostly useful for array proxies, to ensure objects are retrieved via
+  `objectAtContent`.  This is how you could sort items by properties defined on an item controller.
+
+  Example
+
+  ```javascript
+  App.PeopleController = Ember.ArrayController.extend({
+    itemController: 'person',
+
+    sortedPeople: Ember.computed.sort('@this.@each.reversedName', function(personA, personB) {
+      // `reversedName` isn't defined on Person, but we have access to it via
+      // the item controller App.PersonController.  If we'd used
+      // `content.@each.reversedName` above, we would be getting the objects
+      // directly and not have access to `reversedName`.
+      //
+      var reversedNameA = get(personA, 'reversedName'),
+          reversedNameB = get(personB, 'reversedName');
+
+      return Ember.compare(reversedNameA, reversedNameB);
+    })
+  });
+
+  App.PersonController = Ember.ObjectController.extend({
+    reversedName: function () {
+      return reverse(get(this, 'name'));
+    }.property('name')
+  })
+  ```
+
+  Dependent keys whose values are not arrays are treated as regular
+  dependencies: when they change, the computed property is completely
+  recalculated.  It is sometimes useful to have dependent arrays with similar
+  semantics.  Dependent keys which end in `.[]` do not use "one at a time"
+  semantics.  When an item is added or removed from such a dependency, the
+  computed property is completely recomputed.
+
+  Example
+
+  ```javascript
+  Ember.Object.extend({
+    // When `string` is changed, `computed` is completely recomputed.
+    string: 'a string',
+
+    // When an item is added to `array`, `addedItem` is called.
+    array: [],
+
+    // When an item is added to `anotherArray`, `computed` is completely
+    // recomputed.
+    anotherArray: [],
+
+    computed: Ember.reduceComputed('string', 'array', 'anotherArray.[]', {
+      addedItem: addedItemCallback,
+      removedItem: removedItemCallback
+    })
+  });
+  ```

+
+    Computed properties allow you to treat a function like a property:
+
+    ```javascript
+    MyApp.President = Ember.Object.extend({
+      firstName: '',
+      lastName:  '',
+

+      firstName: "Barack",
+      lastName: "Obama"
+    });
+
+    president.get('fullName');    // "Barack Obama"
+    ```
+
+    Treating a function like a property is useful because they can work with
+    bindings, just like any other property.
+
+    Many computed properties have dependencies on other properties. For
+    example, in the above example, the `fullName` property depends on
+    `firstName` and `lastName` to determine its value. You can tell Ember
+    about these dependencies like this:
+
+    ```javascript
+    MyApp.President = Ember.Object.extend({
+      firstName: '',
+      lastName:  '',
+
+      fullName: function() {
+        return this.get('firstName') + ' ' + this.get('lastName');
+
+        // Tell Ember.js that this computed property depends on firstName
+        // and lastName
+      }.property('firstName', 'lastName')
+    });
+    ```
+
+    Make sure you list these dependencies so Ember knows when to update
+    bindings that connect to a computed property. Changing a dependency
+    will not immediately trigger an update of the computed property, but
+    will instead clear the cache so that it is updated when the next `get`
+    is called on the property.

+  The `Ember.Freezable` mixin implements some basic methods for marking an
+  object as frozen. Once an object is frozen it should be read only. No changes
+  may be made the internal state of the object.
+
+  ## Enforcement
+
+  To fully support freezing in your subclass, you must include this mixin and
+  override any method that might alter any property on the object to instead
+  raise an exception. You can check the state of an object by checking the
+  `isFrozen` property.
+
+  Although future versions of JavaScript may support language-level freezing
+  object objects, that is not the case today. Even if an object is freezable,
+  it is still technically possible to modify the object, even though it could
+  break other parts of your application that do not expect a frozen object to
+  change. It is, therefore, very important that you always respect the
+  `isFrozen` property on all freezable objects.
+
+  ## Example Usage
+
+  The example below shows a simple object that implement the `Ember.Freezable`
+  protocol.
+
+  ```javascript
+  Contact = Ember.Object.extend(Ember.Freezable, {
+    firstName: null,
+    lastName: null,
+
+    // swaps the names
+    swapNames: function() {
+      if (this.get('isFrozen')) throw Ember.FROZEN_ERROR;
+      var tmp = this.get('firstName');
+      this.set('firstName', this.get('lastName'));
+      this.set('lastName', tmp);
+      return this;
+    }
+
+  });
+
+  c = Contact.create({ firstName: "John", lastName: "Doe" });
+  c.swapNames();  // returns c
+  c.freeze();
+  c.swapNames();  // EXCEPTION
+  ```
+
+  ## Copying
+
+  Usually the `Ember.Freezable` protocol is implemented in cooperation with the
+  `Ember.Copyable` protocol, which defines a `frozenCopy()` method that will
+  return a frozen object, if the object implements this method as well.
+
+  @class Freezable
+  @namespace Ember
+  @since Ember 0.9
+*/

+  For example, a MappedEnumerable cannot be directly modified but if its

+
+  ## Adding Objects
+
+  To add an object to an enumerable, use the `addObject()` method. This

+
+    These functions will be invoked when a matching `{{action}}` is triggered
+    from within a template and the application's current route is this route.
+
+    Actions can also be invoked from other parts of your application
+    via `ActionHandler#send`.
+
+    The `actions` hash will inherit action handlers from
+    the `actions` hash defined on extended parent classes
+    or mixins rather than just replace the entire hash, e.g.:
+
+    ```js
+    App.CanDisplayBanner = Ember.Mixin.create({
+      actions: {
+        displayBanner: function(msg) {
+          // ...
+        }
+      }
+    });
+
+    App.WelcomeRoute = Ember.Route.extend(App.CanDisplayBanner, {
+      actions: {
+        playMusic: function() {
+          // ...
+        }
+      }
+    });
+
+    // `WelcomeRoute`, when active, will be able to respond
+    // to both actions, since the actions hash is merged rather
+    // then replaced when extending mixins / parent classes.
+    this.send('displayBanner');
+    this.send('playMusic');
+    ```
+
+    Within a Controller, Route, View or Component's action handler,
+    the value of the `this` context is the Controller, Route, View or
+    Component object:
+
+    ```js
+    App.SongRoute = Ember.Route.extend({
+      actions: {
+        myAction: function() {
+          this.controllerFor("song");
+          this.transitionTo("other.route");
+          ...
+        }
+      }
+    });
+    ```
+
+    It is also possible to call `this._super()` from within an
+    action handler if it overrides a handler defined on a parent
+    class or mixin:
+
+    Take for example the following routes:
+
+    ```js
+    App.DebugRoute = Ember.Mixin.create({
+      actions: {
+        debugRouteInformation: function() {
+          console.debug("trololo");
+        }
+      }
+    });
+
+    App.AnnoyingDebugRoute = Ember.Route.extend(App.DebugRoute, {
+      actions: {
+        debugRouteInformation: function() {
+          // also call the debugRouteInformation of mixed in App.DebugRoute
+          this._super();
+
+          // show additional annoyance
+          window.alert(...);
+        }
+      }
+    });
+    ```
+
+    ## Bubbling
+
+    By default, an action will stop bubbling once a handler defined
+    on the `actions` hash handles it. To continue bubbling the action,
+    you must return `true` from the handler:
+
+    ```js
+    App.Router.map(function() {
+      this.resource("album", function() {
+        this.route("song");
+      });

+          // ...
+
+          if (actionShouldAlsoBeTriggeredOnParentRoute) {
+            return true;
+          }
+        }

+  An ArrayProxy wraps any other object that implements `Ember.Array` and/or
+  `Ember.MutableArray,` forwarding all requests. This makes it very useful for
+  a number of binding use cases or other cases where being able to swap
+  out the underlying array is useful.
+
+  A simple example of usage:
+
+  ```javascript
+  var pets = ['dog', 'cat', 'fish'];
+  var ap = Ember.ArrayProxy.create({ content: Ember.A(pets) });
+
+  ap.get('firstObject');                        // 'dog'
+  ap.set('content', ['amoeba', 'paramecium']);
+  ap.get('firstObject');                        // 'amoeba'
+  ```
+
+  This class can also be useful as a layer to transform the contents of
+  an array, as they are accessed. This can be done by overriding
+  `objectAtContent`:
+
+  ```javascript
+  var pets = ['dog', 'cat', 'fish'];
+  var ap = Ember.ArrayProxy.create({
+      content: Ember.A(pets),
+      objectAtContent: function(idx) {
+          return this.get('content').objectAt(idx).toUpperCase();
+      }
+  });
+
+  ap.get('firstObject'); // . 'DOG'

+/**
+  An unordered collection of objects.
+
+  A Set works a bit like an array except that its items are not ordered. You
+  can create a set to efficiently test for membership for an object. You can
+  also iterate through a set just like an array, even accessing objects by
+  index, however there is no guarantee as to their order.
+
+  All Sets are observable via the Enumerable Observer API - which works
+  on any enumerable object including both Sets and Arrays.
+
+  ## Creating a Set
+
+  You can create a set like you would most objects using
+  `new Ember.Set()`. Most new sets you create will be empty, but you can
+  also initialize the set with some content by passing an array or other
+  enumerable of objects to the constructor.
+
+  Finally, you can pass in an existing set and the set will be copied. You
+  can also create a copy of a set by calling `Ember.Set#copy()`.
+
+  ```javascript
+  // creates a new empty set
+  var foundNames = new Ember.Set();
+
+  // creates a set with four names in it.
+  var names = new Ember.Set(["Charles", "Tom", "Juan", "Alex"]); // :P
+
+  // creates a copy of the names set.
+  var namesCopy = new Ember.Set(names);
+
+  // same as above.
+  var anotherNamesCopy = names.copy();
+  ```
+
+  ## Adding/Removing Objects
+
+  You generally add or remove objects from a set using `add()` or
+  `remove()`. You can add any type of object including primitives such as
+  numbers, strings, and booleans.
+
+  Unlike arrays, objects can only exist one time in a set. If you call `add()`
+  on a set with the same object multiple times, the object will only be added
+  once. Likewise, calling `remove()` with the same object multiple times will
+  remove the object the first time and have no effect on future calls until
+  you add the object to the set again.
+
+  NOTE: You cannot add/remove `null` or `undefined` to a set. Any attempt to do
+  so will be ignored.
+
+  In addition to add/remove you can also call `push()`/`pop()`. Push behaves
+  just like `add()` but `pop()`, unlike `remove()` will pick an arbitrary
+  object, remove it and return it. This is a good way to use a set as a job
+  queue when you don't care which order the jobs are executed in.
+
+  ## Testing for an Object
+
+  To test for an object's presence in a set you simply call
+  `Ember.Set#contains()`.
+
+  ## Observing changes
+
+  When using `Ember.Set`, you can observe the `"[]"` property to be
+  alerted whenever the content changes. You can also add an enumerable
+  observer to the set to be notified of specific objects that are added and
+  removed from the set. See [Ember.Enumerable](/api/classes/Ember.Enumerable.html)
+  for more information on enumerables.
+
+  This is often unhelpful. If you are filtering sets of objects, for instance,
+  it is very inefficient to re-filter all of the items each time the set
+  changes. It would be better if you could just adjust the filtered set based
+  on what was changed on the original set. The same issue applies to merging
+  sets, as well.
+
+  ## Other Methods
+
+  `Ember.Set` primary implements other mixin APIs. For a complete reference
+  on the methods you will use with `Ember.Set`, please consult these mixins.
+  The most useful ones will be `Ember.Enumerable` and
+  `Ember.MutableEnumerable` which implement most of the common iterator
+  methods you are used to on Array.
+
+  Note that you can also use the `Ember.Copyable` and `Ember.Freezable`
+  APIs on `Ember.Set` as well. Once a set is frozen it can no longer be
+  modified. The benefit of this is that when you call `frozenCopy()` on it,
+  Ember will avoid making copies of the set. This allows you to write
+  code that can know with certainty when the underlying set data will or
+  will not be modified.

+  ```javascript
+  songs = [
+    {trackNumber: 4, title: 'Ob-La-Di, Ob-La-Da'},
+    {trackNumber: 2, title: 'Back in the U.S.S.R.'},

+
+  songsController.addObject({trackNumber: 1, title: 'Dear Prudence'});
+  songsController.get('firstObject');  // {trackNumber: 1, title: 'Dear Prudence'}
+  ```
+
+  If you add or remove the properties to sort by or change the sort direction the content
+  sort order will be automatically updated.
+
+  ```javascript
+  songsController.set('sortProperties', ['title']);
+  songsController.get('firstObject'); // {trackNumber: 2, title: 'Back in the U.S.S.R.'}

+  songsController.get('firstObject'); // {trackNumber: 4, title: 'Ob-La-Di, Ob-La-Da'}
+  ```
+
+  SortableMixin works by sorting the arrangedContent array, which is the array that
+  arrayProxy displays. Due to the fact that the underlying 'content' array is not changed, that
+  array will not display the sorted list:
+
+   ```javascript
+  songsController.get('content').get('firstObject'); // Returns the unsorted original content
+  songsController.get('firstObject'); // Returns the sorted content.
+  ``` 
+

+/**
+  `Ember.ArrayController` provides a way for you to publish a collection of
+  objects so that you can easily bind to the collection from a Handlebars
+  `#each` helper, an `Ember.CollectionView`, or other controllers.
+
+  The advantage of using an `ArrayController` is that you only have to set up
+  your view bindings once; to change what's displayed, simply swap out the
+  `content` property on the controller.
+
+  For example, imagine you wanted to display a list of items fetched via an XHR
+  request. Create an `Ember.ArrayController` and set its `content` property:
+
+  ```javascript
+  MyApp.listController = Ember.ArrayController.create();
+
+  $.get('people.json', function(data) {
+    MyApp.listController.set('content', data);
+  });
+  ```
+
+  Then, create a view that binds to your new controller:
+
+  ```handlebars
+  {{#each MyApp.listController}}
+    {{firstName}} {{lastName}}
+  {{/each}}
+  ```
+
+  Although you are binding to the controller, the behavior of this controller
+  is to pass through any methods or properties to the underlying array. This
+  capability comes from `Ember.ArrayProxy`, which this class inherits from.
+
+  Sometimes you want to display computed properties within the body of an
+  `#each` helper that depend on the underlying items in `content`, but are not
+  present on those items.   To do this, set `itemController` to the name of a
+  controller (probably an `ObjectController`) that will wrap each individual item.
+
+  For example:
+
+  ```handlebars
+    {{#each post in controller}}
+      <li>{{title}} ({{titleLength}} characters)</li>
+    {{/each}}
+  ```
+
+  ```javascript
+  App.PostsController = Ember.ArrayController.extend({
+    itemController: 'post'
+  });
+
+  App.PostController = Ember.ObjectController.extend({
+    // the `title` property will be proxied to the underlying post.
+
+    titleLength: function() {
+      return this.get('title').length;
+    }.property('title')
+  });
+  ```
+
+  In some cases it is helpful to return a different `itemController` depending
+  on the particular item.  Subclasses can do this by overriding
+  `lookupItemController`.
+
+  For example:
+
+  ```javascript
+  App.MyArrayController = Ember.ArrayController.extend({
+    lookupItemController: function( object ) {
+      if (object.get('isSpecial')) {
+        return "special"; // use App.SpecialController
+      } else {
+        return "regular"; // use App.RegularController
+      }
+    }
+  });
+  ```
+
+  The itemController instances will have a `parentController` property set to
+  the `ArrayController` instance.

+/**
+  `Ember.View` is the class in Ember responsible for encapsulating templates of
+  HTML content, combining templates with data to render as sections of a page's
+  DOM, and registering and responding to user-initiated events.
+
+  ## HTML Tag
+
+  The default HTML tag name used for a view's DOM representation is `div`. This
+  can be customized by setting the `tagName` property. The following view
+  class:
+
+  ```javascript
+  ParagraphView = Ember.View.extend({
+    tagName: 'em'
+  });
+  ```
+
+  Would result in instances with the following HTML:
+
+  ```html
+  <em id="ember1" class="ember-view"></em>
+  ```
+
+  ## HTML `class` Attribute
+
+  The HTML `class` attribute of a view's tag can be set by providing a
+  `classNames` property that is set to an array of strings:
+
+  ```javascript
+  MyView = Ember.View.extend({
+    classNames: ['my-class', 'my-other-class']
+  });
+  ```
+
+  Will result in view instances with an HTML representation of:
+
+  ```html
+  <div id="ember1" class="ember-view my-class my-other-class"></div>
+  ```
+
+  `class` attribute values can also be set by providing a `classNameBindings`
+  property set to an array of properties names for the view. The return value
+  of these properties will be added as part of the value for the view's `class`
+  attribute. These properties can be computed properties:
+
+  ```javascript
+  MyView = Ember.View.extend({
+    classNameBindings: ['propertyA', 'propertyB'],
+    propertyA: 'from-a',
+    propertyB: function() {
+      if (someLogic) { return 'from-b'; }
+    }.property()
+  });
+  ```
+
+  Will result in view instances with an HTML representation of:
+
+  ```html
+  <div id="ember1" class="ember-view from-a from-b"></div>
+  ```
+
+  If the value of a class name binding returns a boolean the property name
+  itself will be used as the class name if the property is true. The class name
+  will not be added if the value is `false` or `undefined`.
+
+  ```javascript
+  MyView = Ember.View.extend({
+    classNameBindings: ['hovered'],
+    hovered: true
+  });
+  ```
+
+  Will result in view instances with an HTML representation of:
+
+  ```html
+  <div id="ember1" class="ember-view hovered"></div>
+  ```
+
+  When using boolean class name bindings you can supply a string value other
+  than the property name for use as the `class` HTML attribute by appending the
+  preferred value after a ":" character when defining the binding:
+
+  ```javascript
+  MyView = Ember.View.extend({
+    classNameBindings: ['awesome:so-very-cool'],
+    awesome: true
+  });
+  ```
+
+  Will result in view instances with an HTML representation of:
+
+  ```html
+  <div id="ember1" class="ember-view so-very-cool"></div>
+  ```
+
+  Boolean value class name bindings whose property names are in a
+  camelCase-style format will be converted to a dasherized format:
+
+  ```javascript
+  MyView = Ember.View.extend({
+    classNameBindings: ['isUrgent'],
+    isUrgent: true
+  });
+  ```
+
+  Will result in view instances with an HTML representation of:
+
+  ```html
+  <div id="ember1" class="ember-view is-urgent"></div>
+  ```
+
+  Class name bindings can also refer to object values that are found by
+  traversing a path relative to the view itself:
+
+  ```javascript
+  MyView = Ember.View.extend({
+    classNameBindings: ['messages.empty']
+    messages: Ember.Object.create({
+      empty: true
+    })
+  });
+  ```
+
+  Will result in view instances with an HTML representation of:
+
+  ```html
+  <div id="ember1" class="ember-view empty"></div>
+  ```
+
+  If you want to add a class name for a property which evaluates to true and
+  and a different class name if it evaluates to false, you can pass a binding
+  like this:
+
+  ```javascript
+  // Applies 'enabled' class when isEnabled is true and 'disabled' when isEnabled is false
+  Ember.View.extend({
+    classNameBindings: ['isEnabled:enabled:disabled']
+    isEnabled: true
+  });
+  ```
+
+  Will result in view instances with an HTML representation of:
+
+  ```html
+  <div id="ember1" class="ember-view enabled"></div>
+  ```
+
+  When isEnabled is `false`, the resulting HTML reprensentation looks like
+  this:
+
+  ```html
+  <div id="ember1" class="ember-view disabled"></div>
+  ```
+
+  This syntax offers the convenience to add a class if a property is `false`:
+
+  ```javascript
+  // Applies no class when isEnabled is true and class 'disabled' when isEnabled is false
+  Ember.View.extend({
+    classNameBindings: ['isEnabled::disabled']
+    isEnabled: true
+  });
+  ```
+
+  Will result in view instances with an HTML representation of:
+
+  ```html
+  <div id="ember1" class="ember-view"></div>
+  ```
+
+  When the `isEnabled` property on the view is set to `false`, it will result
+  in view instances with an HTML representation of:
+
+  ```html
+  <div id="ember1" class="ember-view disabled"></div>
+  ```
+
+  Updates to the the value of a class name binding will result in automatic
+  update of the  HTML `class` attribute in the view's rendered HTML
+  representation. If the value becomes `false` or `undefined` the class name
+  will be removed.
+
+  Both `classNames` and `classNameBindings` are concatenated properties. See
+  [Ember.Object](/api/classes/Ember.Object.html) documentation for more
+  information about concatenated properties.
+
+  ## HTML Attributes
+
+  The HTML attribute section of a view's tag can be set by providing an
+  `attributeBindings` property set to an array of property names on the view.
+  The return value of these properties will be used as the value of the view's
+  HTML associated attribute:
+
+  ```javascript
+  AnchorView = Ember.View.extend({
+    tagName: 'a',
+    attributeBindings: ['href'],
+    href: 'http://google.com'
+  });
+  ```
+
+  Will result in view instances with an HTML representation of:
+
+  ```html
+  <a id="ember1" class="ember-view" href="http://google.com"></a>
+  ```
+
+  If the return value of an `attributeBindings` monitored property is a boolean
+  the property will follow HTML's pattern of repeating the attribute's name as
+  its value:
+
+  ```javascript
+  MyTextInput = Ember.View.extend({
+    tagName: 'input',
+    attributeBindings: ['disabled'],
+    disabled: true
+  });
+  ```
+
+  Will result in view instances with an HTML representation of:
+
+  ```html
+  <input id="ember1" class="ember-view" disabled="disabled" />
+  ```
+
+  `attributeBindings` can refer to computed properties:
+
+  ```javascript
+  MyTextInput = Ember.View.extend({
+    tagName: 'input',
+    attributeBindings: ['disabled'],
+    disabled: function() {
+      if (someLogic) {
+        return true;
+      } else {
+        return false;
+      }
+    }.property()
+  });
+  ```
+
+  Updates to the the property of an attribute binding will result in automatic
+  update of the  HTML attribute in the view's rendered HTML representation.
+
+  `attributeBindings` is a concatenated property. See [Ember.Object](/api/classes/Ember.Object.html)
+  documentation for more information about concatenated properties.
+
+  ## Templates
+
+  The HTML contents of a view's rendered representation are determined by its
+  template. Templates can be any function that accepts an optional context
+  parameter and returns a string of HTML that will be inserted within the
+  view's tag. Most typically in Ember this function will be a compiled
+  `Ember.Handlebars` template.
+
+  ```javascript
+  AView = Ember.View.extend({
+    template: Ember.Handlebars.compile('I am the template')
+  });
+  ```
+
+  Will result in view instances with an HTML representation of:
+
+  ```html
+  <div id="ember1" class="ember-view">I am the template</div>
+  ```
+
+  Within an Ember application is more common to define a Handlebars templates as
+  part of a page:
+
+  ```html
+  <script type='text/x-handlebars' data-template-name='some-template'>
+    Hello
+  </script>
+  ```
+
+  And associate it by name using a view's `templateName` property:
+
+  ```javascript
+  AView = Ember.View.extend({
+    templateName: 'some-template'
+  });
+  ```
+
+  If you have nested resources, your Handlebars template will look like this:
+
+  ```html
+  <script type='text/x-handlebars' data-template-name='posts/new'>
+    <h1>New Post</h1>
+  </script>
+  ```
+
+  And `templateName` property:
+
+  ```javascript
+  AView = Ember.View.extend({
+    templateName: 'posts/new'
+  });
+  ```
+
+  Using a value for `templateName` that does not have a Handlebars template
+  with a matching `data-template-name` attribute will throw an error.
+
+  For views classes that may have a template later defined (e.g. as the block
+  portion of a `{{view}}` Handlebars helper call in another template or in
+  a subclass), you can provide a `defaultTemplate` property set to compiled
+  template function. If a template is not later provided for the view instance
+  the `defaultTemplate` value will be used:
+
+  ```javascript
+  AView = Ember.View.extend({
+    defaultTemplate: Ember.Handlebars.compile('I was the default'),
+    template: null,
+    templateName: null
+  });
+  ```
+
+  Will result in instances with an HTML representation of:
+
+  ```html
+  <div id="ember1" class="ember-view">I was the default</div>
+  ```
+
+  If a `template` or `templateName` is provided it will take precedence over
+  `defaultTemplate`:
+
+  ```javascript
+  AView = Ember.View.extend({
+    defaultTemplate: Ember.Handlebars.compile('I was the default')
+  });
+
+  aView = AView.create({
+    template: Ember.Handlebars.compile('I was the template, not default')
+  });
+  ```
+
+  Will result in the following HTML representation when rendered:
+
+  ```html
+  <div id="ember1" class="ember-view">I was the template, not default</div>
+  ```
+
+  ## View Context
+
+  The default context of the compiled template is the view's controller:
+
+  ```javascript
+  AView = Ember.View.extend({
+    template: Ember.Handlebars.compile('Hello {{excitedGreeting}}')
+  });
+
+  aController = Ember.Object.create({
+    firstName: 'Barry',
+    excitedGreeting: function() {
+      return this.get("content.firstName") + "!!!"
+    }.property()
+  });
+
+  aView = AView.create({
+    controller: aController,
+  });
+  ```
+
+  Will result in an HTML representation of:
+
+  ```html
+  <div id="ember1" class="ember-view">Hello Barry!!!</div>
+  ```
+
+  A context can also be explicitly supplied through the view's `context`
+  property. If the view has neither `context` nor `controller` properties, the
+  `parentView`'s context will be used.
+
+  ## Layouts
+
+  Views can have a secondary template that wraps their main template. Like
+  primary templates, layouts can be any function that  accepts an optional
+  context parameter and returns a string of HTML that will be inserted inside
+  view's tag. Views whose HTML element is self closing (e.g. `<input />`)
+  cannot have a layout and this property will be ignored.
+
+  Most typically in Ember a layout will be a compiled `Ember.Handlebars`
+  template.
+
+  A view's layout can be set directly with the `layout` property or reference
+  an existing Handlebars template by name with the `layoutName` property.
+
+  A template used as a layout must contain a single use of the Handlebars
+  `{{yield}}` helper. The HTML contents of a view's rendered `template` will be
+  inserted at this location:
+
+  ```javascript
+  AViewWithLayout = Ember.View.extend({
+    layout: Ember.Handlebars.compile("<div class='my-decorative-class'>{{yield}}</div>")
+    template: Ember.Handlebars.compile("I got wrapped"),
+  });
+  ```
+
+  Will result in view instances with an HTML representation of:
+
+  ```html
+  <div id="ember1" class="ember-view">
+    <div class="my-decorative-class">
+      I got wrapped
+    </div>
+  </div>
+  ```
+
+  See [Ember.Handlebars.helpers.yield](/api/classes/Ember.Handlebars.helpers.html#method_yield)
+  for more information.
+
+  ## Responding to Browser Events
+
+  Views can respond to user-initiated events in one of three ways: method
+  implementation, through an event manager, and through `{{action}}` helper use
+  in their template or layout.
+
+  ### Method Implementation
+
+  Views can respond to user-initiated events by implementing a method that
+  matches the event name. A `jQuery.Event` object will be passed as the
+  argument to this method.
+
+  ```javascript
+  AView = Ember.View.extend({
+    click: function(event) {
+      // will be called when when an instance's
+      // rendered element is clicked
+    }
+  });
+  ```
+
+  ### Event Managers
+
+  Views can define an object as their `eventManager` property. This object can
+  then implement methods that match the desired event names. Matching events
+  that occur on the view's rendered HTML or the rendered HTML of any of its DOM
+  descendants will trigger this method. A `jQuery.Event` object will be passed
+  as the first argument to the method and an  `Ember.View` object as the
+  second. The `Ember.View` will be the view whose rendered HTML was interacted
+  with. This may be the view with the `eventManager` property or one of its
+  descendent views.
+
+  ```javascript
+  AView = Ember.View.extend({
+    eventManager: Ember.Object.create({
+      doubleClick: function(event, view) {
+        // will be called when when an instance's
+        // rendered element or any rendering
+        // of this views's descendent
+        // elements is clicked
+      }
+    })
+  });
+  ```
+
+  An event defined for an event manager takes precedence over events of the
+  same name handled through methods on the view.
+
+  ```javascript
+  AView = Ember.View.extend({
+    mouseEnter: function(event) {
+      // will never trigger.
+    },
+    eventManager: Ember.Object.create({
+      mouseEnter: function(event, view) {
+        // takes precedence over AView#mouseEnter
+      }
+    })
+  });
+  ```
+
+  Similarly a view's event manager will take precedence for events of any views
+  rendered as a descendent. A method name that matches an event name will not
+  be called if the view instance was rendered inside the HTML representation of
+  a view that has an `eventManager` property defined that handles events of the
+  name. Events not handled by the event manager will still trigger method calls
+  on the descendent.
+
+  ```javascript
+  OuterView = Ember.View.extend({
+    template: Ember.Handlebars.compile("outer {{#view InnerView}}inner{{/view}} outer"),
+    eventManager: Ember.Object.create({
+      mouseEnter: function(event, view) {
+        // view might be instance of either
+        // OuterView or InnerView depending on
+        // where on the page the user interaction occured
+      }
+    })
+  });
+
+  InnerView = Ember.View.extend({
+    click: function(event) {
+      // will be called if rendered inside
+      // an OuterView because OuterView's
+      // eventManager doesn't handle click events
+    },
+    mouseEnter: function(event) {
+      // will never be called if rendered inside
+      // an OuterView.
+    }
+  });
+  ```
+
+  ### Handlebars `{{action}}` Helper
+
+  See [Handlebars.helpers.action](/api/classes/Ember.Handlebars.helpers.html#method_action).
+
+  ### Event Names
+
+  All of the event handling approaches described above respond to the same set
+  of events. The names of the built-in events are listed below. (The hash of
+  built-in events exists in `Ember.EventDispatcher`.) Additional, custom events
+  can be registered by using `Ember.Application.customEvents`.
+
+  Touch events:
+
+  * `touchStart`
+  * `touchMove`
+  * `touchEnd`
+  * `touchCancel`
+
+  Keyboard events
+
+  * `keyDown`
+  * `keyUp`
+  * `keyPress`
+
+  Mouse events
+
+  * `mouseDown`
+  * `mouseUp`
+  * `contextMenu`
+  * `click`
+  * `doubleClick`
+  * `mouseMove`
+  * `focusIn`
+  * `focusOut`
+  * `mouseEnter`
+  * `mouseLeave`
+
+  Form events:
+
+  * `submit`
+  * `change`
+  * `focusIn`
+  * `focusOut`
+  * `input`
+
+  HTML5 drag and drop events:
+
+  * `dragStart`
+  * `drag`
+  * `dragEnter`
+  * `dragLeave`
+  * `drop`
+  * `dragEnd`
+
+  ## Handlebars `{{view}}` Helper
+
+  Other `Ember.View` instances can be included as part of a view's template by
+  using the `{{view}}` Handlebars helper. See [Ember.Handlebars.helpers.view](/api/classes/Ember.Handlebars.helpers.html#method_view)
+  for additional information.

+  A `ContainerView` is an `Ember.View` subclass that implements `Ember.MutableArray`
+  allowing programmatic management of its child views.
+
+  ## Setting Initial Child Views
+
+  The initial array of child views can be set in one of two ways. You can
+  provide a `childViews` property at creation time that contains instance of
+  `Ember.View`:
+
+  ```javascript
+  aContainer = Ember.ContainerView.create({
+    childViews: [Ember.View.create(), Ember.View.create()]
+  });
+  ```
+
+  You can also provide a list of property names whose values are instances of
+  `Ember.View`:
+
+  ```javascript
+  aContainer = Ember.ContainerView.create({
+    childViews: ['aView', 'bView', 'cView'],
+    aView: Ember.View.create(),
+    bView: Ember.View.create(),
+    cView: Ember.View.create()
+  });
+  ```
+
+  The two strategies can be combined:
+
+  ```javascript
+  aContainer = Ember.ContainerView.create({
+    childViews: ['aView', Ember.View.create()],
+    aView: Ember.View.create()
+  });
+  ```
+
+  Each child view's rendering will be inserted into the container's rendered
+  HTML in the same order as its position in the `childViews` property.
+
+  ## Adding and Removing Child Views
+
+  The container view implements `Ember.MutableArray` allowing programmatic management of its child views.
+
+  To remove a view, pass that view into a `removeObject` call on the container view.
+
+  Given an empty `<body>` the following code
+
+  ```javascript
+  aContainer = Ember.ContainerView.create({
+    classNames: ['the-container'],
+    childViews: ['aView', 'bView'],
+    aView: Ember.View.create({
+      template: Ember.Handlebars.compile("A")
+    }),
+    bView: Ember.View.create({
+      template: Ember.Handlebars.compile("B")
+    })
+  });
+
+  aContainer.appendTo('body');
+  ```
+
+  Results in the HTML
+
+  ```html
+  <div class="ember-view the-container">
+    <div class="ember-view">A</div>
+    <div class="ember-view">B</div>
+  </div>
+  ```
+
+  Removing a view
+
+  ```javascript
+  aContainer.toArray();  // [aContainer.aView, aContainer.bView]
+  aContainer.removeObject(aContainer.get('bView'));
+  aContainer.toArray();  // [aContainer.aView]
+  ```
+
+  Will result in the following HTML
+
+  ```html
+  <div class="ember-view the-container">
+    <div class="ember-view">A</div>
+  </div>
+  ```
+
+  Similarly, adding a child view is accomplished by adding `Ember.View` instances to the
+  container view.
+
+  Given an empty `<body>` the following code
+
+  ```javascript
+  aContainer = Ember.ContainerView.create({
+    classNames: ['the-container'],
+    childViews: ['aView', 'bView'],
+    aView: Ember.View.create({
+      template: Ember.Handlebars.compile("A")
+    }),
+    bView: Ember.View.create({
+      template: Ember.Handlebars.compile("B")
+    })
+  });
+
+  aContainer.appendTo('body');
+  ```
+
+  Results in the HTML
+
+  ```html
+  <div class="ember-view the-container">
+    <div class="ember-view">A</div>
+    <div class="ember-view">B</div>
+  </div>
+  ```
+
+  Adding a view
+
+  ```javascript
+  AnotherViewClass = Ember.View.extend({
+    template: Ember.Handlebars.compile("Another view")
+  });
+
+  aContainer.toArray();  // [aContainer.aView, aContainer.bView]
+  aContainer.pushObject(AnotherViewClass.create());
+  aContainer.toArray(); // [aContainer.aView, aContainer.bView, <AnotherViewClass instance>]
+  ```
+
+  Will result in the following HTML
+
+  ```html
+  <div class="ember-view the-container">
+    <div class="ember-view">A</div>
+    <div class="ember-view">B</div>
+    <div class="ember-view">Another view</div>
+  </div>
+  ```
+
+  ## Templates and Layout
+
+  A `template`, `templateName`, `defaultTemplate`, `layout`, `layoutName` or
+  `defaultLayout` property on a container view will not result in the template
+  or layout being rendered. The HTML contents of a `Ember.ContainerView`'s DOM
+  representation will only be the rendered HTML of its child views.

+
+/**
+  `Ember.CollectionView` is an `Ember.View` descendent responsible for managing
+  a collection (an array or array-like object) by maintaining a child view object
+  and associated DOM representation for each item in the array and ensuring
+  that child views and their associated rendered HTML are updated when items in
+  the array are added, removed, or replaced.
+
+  ## Setting content
+
+  The managed collection of objects is referenced as the `Ember.CollectionView`
+  instance's `content` property.
+
+  ```javascript
+  someItemsView = Ember.CollectionView.create({
+    content: ['A', 'B','C']
+  })
+  ```
+
+  The view for each item in the collection will have its `content` property set
+  to the item.
+
+  ## Specifying itemViewClass
+
+  By default the view class for each item in the managed collection will be an
+  instance of `Ember.View`. You can supply a different class by setting the
+  `CollectionView`'s `itemViewClass` property.
+
+  Given an empty `<body>` and the following code:
+
+  ```javascript
+  someItemsView = Ember.CollectionView.create({
+    classNames: ['a-collection'],
+    content: ['A','B','C'],
+    itemViewClass: Ember.View.extend({
+      template: Ember.Handlebars.compile("the letter: {{view.content}}")
+    })
+  });
+
+  someItemsView.appendTo('body');
+  ```
+
+  Will result in the following HTML structure
+
+  ```html
+  <div class="ember-view a-collection">
+    <div class="ember-view">the letter: A</div>
+    <div class="ember-view">the letter: B</div>
+    <div class="ember-view">the letter: C</div>
+  </div>
+  ```
+
+  ## Automatic matching of parent/child tagNames
+
+  Setting the `tagName` property of a `CollectionView` to any of
+  "ul", "ol", "table", "thead", "tbody", "tfoot", "tr", or "select" will result
+  in the item views receiving an appropriately matched `tagName` property.
+
+  Given an empty `<body>` and the following code:
+
+  ```javascript
+  anUnorderedListView = Ember.CollectionView.create({
+    tagName: 'ul',
+    content: ['A','B','C'],
+    itemViewClass: Ember.View.extend({
+      template: Ember.Handlebars.compile("the letter: {{view.content}}")
+    })
+  });
+
+  anUnorderedListView.appendTo('body');
+  ```
+
+  Will result in the following HTML structure
+
+  ```html
+  <ul class="ember-view a-collection">
+    <li class="ember-view">the letter: A</li>
+    <li class="ember-view">the letter: B</li>
+    <li class="ember-view">the letter: C</li>
+  </ul>
+  ```
+
+  Additional `tagName` pairs can be provided by adding to
+  `Ember.CollectionView.CONTAINER_MAP `
+
+  ```javascript
+  Ember.CollectionView.CONTAINER_MAP['article'] = 'section'
+  ```
+
+  ## Programmatic creation of child views
+
+  For cases where additional customization beyond the use of a single
+  `itemViewClass` or `tagName` matching is required CollectionView's
+  `createChildView` method can be overidden:
+
+  ```javascript
+  CustomCollectionView = Ember.CollectionView.extend({
+    createChildView: function(viewClass, attrs) {
+      if (attrs.content.kind == 'album') {
+        viewClass = App.AlbumView;
+      } else {
+        viewClass = App.SongView;
+      }
+      return this._super(viewClass, attrs);
+    }
+  });
+  ```
+
+  ## Empty View
+
+  You can provide an `Ember.View` subclass to the `Ember.CollectionView`
+  instance as its `emptyView` property. If the `content` property of a
+  `CollectionView` is set to `null` or an empty array, an instance of this view
+  will be the `CollectionView`s only child.
+
+  ```javascript
+  aListWithNothing = Ember.CollectionView.create({
+    classNames: ['nothing']
+    content: null,
+    emptyView: Ember.View.extend({
+      template: Ember.Handlebars.compile("The collection is empty")
+    })
+  });
+
+  aListWithNothing.appendTo('body');
+  ```
+
+  Will result in the following HTML structure
+
+  ```html
+  <div class="ember-view nothing">
+    <div class="ember-view">
+      The collection is empty
+    </div>
+  </div>
+  ```
+
+  ## Adding and Removing items
+
+  The `childViews` property of a `CollectionView` should not be directly
+  manipulated. Instead, add, remove, replace items from its `content` property.
+  This will trigger appropriate changes to its rendered HTML.

+
+/**
+  An `Ember.Component` is a view that is completely
+  isolated. Property access in its templates go
+  to the view object and actions are targeted at
+  the view object. There is no access to the
+  surrounding context or outer controller; all
+  contextual information must be passed in.
+
+  The easiest way to create an `Ember.Component` is via
+  a template. If you name a template
+  `components/my-foo`, you will be able to use
+  `{{my-foo}}` in other templates, which will make
+  an instance of the isolated component.
+
+  ```handlebars
+  {{app-profile person=currentUser}}
+  ```
+
+  ```handlebars
+  <!-- app-profile template -->
+  <h1>{{person.title}}</h1>
+  <img {{bind-attr src=person.avatar}}>
+  <p class='signature'>{{person.signature}}</p>
+  ```
+
+  You can use `yield` inside a template to
+  include the **contents** of any block attached to
+  the component. The block will be executed in the
+  context of the surrounding context or outer controller:
+
+  ```handlebars
+  {{#app-profile person=currentUser}}
+    <p>Admin mode</p>
+    {{! Executed in the controller's context. }}
+  {{/app-profile}}
+  ```
+
+  ```handlebars
+  <!-- app-profile template -->
+  <h1>{{person.title}}</h1>
+  {{! Executed in the components context. }}
+  {{yield}} {{! block contents }}
+  ```
+
+  If you want to customize the component, in order to
+  handle events or actions, you implement a subclass
+  of `Ember.Component` named after the name of the
+  component. Note that `Component` needs to be appended to the name of
+  your subclass like `AppProfileComponent`.
+
+  For example, you could implement the action
+  `hello` for the `app-profile` component:
+
+  ```javascript
+  App.AppProfileComponent = Ember.Component.extend({
+    actions: {
+      hello: function(name) {
+        console.log("Hello", name);
+      }
+    }
+  });
+  ```
+
+  And then use it in the component's template:
+
+  ```handlebars
+  <!-- app-profile template -->
+
+  <h1>{{person.title}}</h1>
+  {{yield}} <!-- block contents -->
+
+  <button {{action 'hello' person.name}}>
+    Say Hello to {{person.name}}
+  </button>
+  ```
+
+  Components must have a `-` in their name to avoid
+  conflicts with built-in controls that wrap HTML
+  elements. This is consistent with the same
+  requirement in web components.

+        } else {
+          this.sendAction('stop');
+        }
+      }
+    });
+    ```
+
+    When used inside a template these component actions are configured to
+    trigger actions in the outer application context:
+
+    ```handlebars
+    {{! application.hbs }}
+    {{play-button play="musicStarted" stop="musicStopped"}}
+    ```
+
+    When the component receives a browser `click` event it translate this
+    interaction into application-specific semantics ("play" or "stop") and
+    triggers the specified action name on the controller for the template
+    where the component is used: 
+
+
+    ```javascript
+    App.ApplicationController = Ember.Controller.extend({
+      actions: {
+        musicStarted: function(){
+          // called when the play button is clicked

+      }
+    });
+    ```
+
+    If no action name is passed to `sendAction` a default name of "action"

+`Ember.ViewTargetActionSupport` is a mixin that can be included in a

+for the action's target: the view's controller; and the context that is
+sent with the action: the view's context.
+
+Note: In normal Ember usage, the `{{action}}` helper is usually the best
+choice. This mixin is most often useful when you are doing more complex
+event handling in custom View subclasses.

+
+```javascript

+  }
+});
+```
+
+The `action` can be provided as properties of an optional object argument
+to `triggerAction` as well.
+
+```javascript
+App.SaveButtonView = Ember.View.extend(Ember.ViewTargetActionSupport, {
+  click: function() {

+/**
+  Register a bound handlebars helper. Bound helpers behave similarly to regular
+  handlebars helpers, with the added ability to re-render when the underlying data
+  changes.
+
+  ## Simple example
+
+  ```javascript
+  Ember.Handlebars.registerBoundHelper('capitalize', function(value) {
+    return value.toUpperCase();
+  });
+  ```
+
+  The above bound helper can be used inside of templates as follows:
+
+  ```handlebars
+  {{capitalize name}}
+  ```
+
+  In this case, when the `name` property of the template's context changes,
+  the rendered value of the helper will update to reflect this change.
+
+  ## Example with options
+
+  Like normal handlebars helpers, bound helpers have access to the options
+  passed into the helper call.
+
+  ```javascript
+  Ember.Handlebars.registerBoundHelper('repeat', function(value, options) {
+    var count = options.hash.count;
+    var a = [];
+    while(a.length < count) {
+        a.push(value);
+    }
+    return a.join('');
+  });
+  ```
+
+  This helper could be used in a template as follows:
+
+  ```handlebars
+  {{repeat text count=3}}
+  ```
+
+  ## Example with bound options
+
+  Bound hash options are also supported. Example:
+
+  ```handlebars
+  {{repeat text countBinding="numRepeats"}}
+  ```
+
+  In this example, count will be bound to the value of
+  the `numRepeats` property on the context. If that property
+  changes, the helper will be re-rendered.
+
+  ## Example with extra dependencies
+
+  The `Ember.Handlebars.registerBoundHelper` method takes a variable length
+  third parameter which indicates extra dependencies on the passed in value.
+  This allows the handlebars helper to update when these dependencies change.
+
+  ```javascript
+  Ember.Handlebars.registerBoundHelper('capitalizeName', function(value) {
+    return value.get('name').toUpperCase();
+  }, 'name');
+  ```
+
+  ## Example with multiple bound properties
+
+  `Ember.Handlebars.registerBoundHelper` supports binding to
+  multiple properties, e.g.:
+
+  ```javascript
+  Ember.Handlebars.registerBoundHelper('concatenate', function() {
+    var values = Array.prototype.slice.call(arguments, 0, -1);
+    return values.join('||');
+  });
+  ```
+
+  Which allows for template syntax such as `{{concatenate prop1 prop2}}` or
+  `{{concatenate prop1 prop2 prop3}}`. If any of the properties change,
+  the helpr will re-render.  Note that dependency keys cannot be
+  using in conjunction with multi-property helpers, since it is ambiguous
+  which property the dependent keys would belong to.
+
+  ## Use with unbound helper
+
+  The `{{unbound}}` helper can be used with bound helper invocations
+  to render them in their unbound form, e.g.
+
+  ```handlebars
+  {{unbound capitalize name}}
+  ```
+
+  In this example, if the name property changes, the helper
+  will not re-render.
+
+  ## Use with blocks not supported
+
+  Bound helpers do not support use with Handlebars blocks or
+  the addition of child views of any kind.

+/**
+  Use the `{{with}}` helper when you want to scope context. Take the following code as an example:
+
+  ```handlebars
+  <h5>{{user.name}}</h5>
+
+  <div class="role">
+    <h6>{{user.role.label}}</h6>
+    <span class="role-id">{{user.role.id}}</span>
+
+    <p class="role-desc">{{user.role.description}}</p>
+  </div>
+  ```
+
+  `{{with}}` can be our best friend in these cases, 
+  instead of writing `user.role.*` over and over, we use `{{#with user.role}}`.
+  Now the context within the `{{#with}} .. {{/with}}` block is `user.role` so you can do the following:
+
+  ```handlebars
+  <h5>{{user.name}}</h5>
+
+  <div class="role">
+    {{#with user.role}}
+      <h6>{{label}}</h6>
+      <span class="role-id">{{id}}</span>
+
+      <p class="role-desc">{{description}}</p>
+    {{/with}}
+  </div>
+  ```
+
+  ### `as` operator
+
+  This operator aliases the scope to a new name. It's helpful for semantic clarity and to retain 
+  default scope or to reference from another `{{with}}` block.
+
+  ```handlebars
+  // posts might not be
+  {{#with user.posts as blogPosts}}
+    <div class="notice">
+      There are {{blogPosts.length}} blog posts written by {{user.name}}.
+    </div>
+
+    {{#each post in blogPosts}}
+      <li>{{post.title}}</li>
+    {{/each}}
+  {{/with}}
+  ```
+
+  Without the `as` operator, it would be impossible to reference `user.name` in the example above.
+
+  NOTE: The alias should not reuse a name from the bound property path.
+  For example: `{{#with foo.bar as foo}}` is not supported because it attempts to alias using
+  the first part of the property path, `foo`. Instead, use `{{#with foo.bar as baz}}`.
+
+  ### `controller` option
+
+  Adding `controller='something'` instructs the `{{with}}` helper to create and use an instance of
+  the specified controller with the new context as its content.
+
+  This is very similar to using an `itemController` option with the `{{each}}` helper.
+
+  ```handlebars
+  {{#with users.posts controller='userBlogPosts'}}
+    {{!- The current context is wrapped in our controller instance }}
+  {{/with}}
+  ```
+
+  In the above example, the template provided to the `{{with}}` block is now wrapped in the
+  `userBlogPost` controller, which provides a very elegant way to decorate the context with custom
+  functions/properties.

+  `bind-attr` allows you to create a binding between DOM element attributes and
+  Ember objects. For example:
+
+  ```handlebars
+  <img {{bind-attr src="imageUrl" alt="imageTitle"}}>
+  ```
+
+  The above handlebars template will fill the `<img>`'s `src` attribute will
+  the value of the property referenced with `"imageUrl"` and its `alt`
+  attribute with the value of the property referenced with `"imageTitle"`.
+
+  If the rendering context of this template is the following object:
+
+  ```javascript
+  {
+    imageUrl: 'http://lolcats.info/haz-a-funny',
+    imageTitle: 'A humorous image of a cat'
+  }
+  ```
+
+  The resulting HTML output will be:
+
+  ```html
+  <img src="http://lolcats.info/haz-a-funny" alt="A humorous image of a cat">
+  ```
+
+  `bind-attr` cannot redeclare existing DOM element attributes. The use of `src`
+  in the following `bind-attr` example will be ignored and the hard coded value
+  of `src="/failwhale.gif"` will take precedence:
+
+  ```handlebars
+  <img src="/failwhale.gif" {{bind-attr src="imageUrl" alt="imageTitle"}}>
+  ```
+
+  ### `bind-attr` and the `class` attribute
+
+  `bind-attr` supports a special syntax for handling a number of cases unique
+  to the `class` DOM element attribute. The `class` attribute combines
+  multiple discrete values into a single attribute as a space-delimited
+  list of strings. Each string can be:
+
+  * a string return value of an object's property.
+  * a boolean return value of an object's property
+  * a hard-coded value
+
+  A string return value works identically to other uses of `bind-attr`. The
+  return value of the property will become the value of the attribute. For
+  example, the following view and template:
+
+  ```javascript
+    AView = Ember.View.extend({
+      someProperty: function() {
+        return "aValue";
+      }.property()
+    })
+  ```
+
+  ```handlebars
+  <img {{bind-attr class="view.someProperty}}>
+  ```
+
+  Result in the following rendered output:
+
+  ```html
+  <img class="aValue">
+  ```
+
+  A boolean return value will insert a specified class name if the property
+  returns `true` and remove the class name if the property returns `false`.
+
+  A class name is provided via the syntax
+  `somePropertyName:class-name-if-true`.
+
+  ```javascript
+  AView = Ember.View.extend({
+    someBool: true
+  })
+  ```
+
+  ```handlebars
+  <img {{bind-attr class="view.someBool:class-name-if-true"}}>
+  ```
+
+  Result in the following rendered output:
+
+  ```html
+  <img class="class-name-if-true">
+  ```
+
+  An additional section of the binding can be provided if you want to
+  replace the existing class instead of removing it when the boolean
+  value changes:
+
+  ```handlebars
+  <img {{bind-attr class="view.someBool:class-name-if-true:class-name-if-false"}}>
+  ```
+
+  A hard-coded value can be used by prepending `:` to the desired
+  class name: `:class-name-to-always-apply`.
+
+  ```handlebars
+  <img {{bind-attr class=":class-name-to-always-apply"}}>
+  ```
+
+  Results in the following rendered output:
+
+  ```html
+  <img class="class-name-to-always-apply">
+  ```
+
+  All three strategies - string return value, boolean return value, and
+  hard-coded value – can be combined in a single declaration:
+
+  ```handlebars
+  <img {{bind-attr class=":class-name-to-always-apply view.someBool:class-name-if-true view.someProperty"}}>
+  ```

+  options to the `Ember.View`'s `create` method and using the supplied block as
+  the view's own template.
+
+  An empty `<body>` and the following template:
+
+  ```handlebars
+  A span:
+  {{#view tagName="span"}}
+    hello.
+  {{/view}}
+  ```
+
+  Will result in HTML structure:
+
+  ```html
+  <body>
+    <!-- Note: the handlebars template script
+         also results in a rendered Ember.View
+         which is the outer <div> here -->
+
+    <div class="ember-view">
+      A span:
+      <span id="ember1" class="ember-view">
+        Hello.
+      </span>
+    </div>
+  </body>
+  ```
+
+  ### `parentView` setting
+
+  The `parentView` property of the new `Ember.View` instance created through
+  `{{view}}` will be set to the `Ember.View` instance of the template where
+  `{{view}}` was called.
+
+  ```javascript
+  aView = Ember.View.create({
+    template: Ember.Handlebars.compile("{{#view}} my parent: {{parentView.elementId}} {{/view}}")
+  });
+
+  aView.appendTo('body');
+  ```
+
+  Will result in HTML structure:
+
+  ```html
+  <div id="ember1" class="ember-view">
+    <div id="ember2" class="ember-view">
+      my parent: ember1
+    </div>
+  </div>
+  ```
+
+  ### Setting CSS id and class attributes
+
+  The HTML `id` attribute can be set on the `{{view}}`'s resulting element with
+  the `id` option. This option will _not_ be passed to `Ember.View.create`.
+
+  ```handlebars
+  {{#view tagName="span" id="a-custom-id"}}
+    hello.
+  {{/view}}
+  ```
+
+  Results in the following HTML structure:
+
+  ```html
+  <div class="ember-view">
+    <span id="a-custom-id" class="ember-view">
+      hello.
+    </span>
+  </div>
+  ```
+
+  The HTML `class` attribute can be set on the `{{view}}`'s resulting element
+  with the `class` or `classNameBindings` options. The `class` option will
+  directly set the CSS `class` attribute and will not be passed to
+  `Ember.View.create`. `classNameBindings` will be passed to `create` and use
+  `Ember.View`'s class name binding functionality:
+
+  ```handlebars
+  {{#view tagName="span" class="a-custom-class"}}
+    hello.
+  {{/view}}
+  ```
+
+  Results in the following HTML structure:
+
+  ```html
+  <div class="ember-view">
+    <span id="ember2" class="ember-view a-custom-class">
+      hello.
+    </span>
+  </div>
+  ```
+
+  ### Supplying a different view class
+
+  `{{view}}` can take an optional first argument before its supplied options to
+  specify a path to a custom view class.
+
+  ```handlebars
+  {{#view "MyApp.CustomView"}}
+    hello.
+  {{/view}}
+  ```
+
+  The first argument can also be a relative path accessible from the current
+  context.
+
+  ```javascript
+  MyApp = Ember.Application.create({});
+  MyApp.OuterView = Ember.View.extend({
+    innerViewClass: Ember.View.extend({
+      classNames: ['a-custom-view-class-as-property']
+    }),
+    template: Ember.Handlebars.compile('{{#view "view.innerViewClass"}} hi {{/view}}')
+  });
+
+  MyApp.OuterView.create().appendTo('body');
+  ```
+
+  Will result in the following HTML:
+
+  ```html
+  <div id="ember1" class="ember-view">
+    <div id="ember2" class="ember-view a-custom-view-class-as-property">
+      hi
+    </div>
+  </div>
+  ```
+
+  ### Blockless use
+
+  If you supply a custom `Ember.View` subclass that specifies its own template
+  or provide a `templateName` option to `{{view}}` it can be used without
+  supplying a block. Attempts to use both a `templateName` option and supply a
+  block will throw an error.
+
+  ```handlebars
+  {{view "MyApp.ViewWithATemplateDefined"}}
+  ```
+
+  ### `viewName` property
+
+  You can supply a `viewName` option to `{{view}}`. The `Ember.View` instance
+  will be referenced as a property of its parent view by this name.
+
+  ```javascript
+  aView = Ember.View.create({
+    template: Ember.Handlebars.compile('{{#view viewName="aChildByName"}} hi {{/view}}')
+  });
+
+  aView.appendTo('body');
+  aView.get('aChildByName') // the instance of Ember.View created by {{view}} helper
+  ```
+
+  @method view
+  @for Ember.Handlebars.helpers

+  `{{collection}}` is a `Ember.Handlebars` helper for adding instances of
+  `Ember.CollectionView` to a template. See [Ember.CollectionView](/api/classes/Ember.CollectionView.html)
+   for additional information on how a `CollectionView` functions.
+
+  `{{collection}}`'s primary use is as a block helper with a `contentBinding`
+  option pointing towards an `Ember.Array`-compatible object. An `Ember.View`
+  instance will be created for each item in its `content` property. Each view
+  will have its own `content` property set to the appropriate item in the
+  collection.
+
+  The provided block will be applied as the template for each item's view.
+
+  Given an empty `<body>` the following template:
+
+  ```handlebars
+  {{#collection contentBinding="App.items"}}
+    Hi {{view.content.name}}
+  {{/collection}}
+  ```
+
+  And the following application code
+
+  ```javascript
+  App = Ember.Application.create()
+  App.items = [
+    Ember.Object.create({name: 'Dave'}),
+    Ember.Object.create({name: 'Mary'}),
+    Ember.Object.create({name: 'Sara'})
+  ]
+  ```
+
+  Will result in the HTML structure below
+
+  ```html
+  <div class="ember-view">
+    <div class="ember-view">Hi Dave</div>
+    <div class="ember-view">Hi Mary</div>
+    <div class="ember-view">Hi Sara</div>
+  </div>
+  ```
+
+  ### Blockless use in a collection
+
+  If you provide an `itemViewClass` option that has its own `template` you can
+  omit the block.
+
+  The following template:
+
+  ```handlebars
+  {{collection contentBinding="App.items" itemViewClass="App.AnItemView"}}
+  ```
+
+  And application code
+
+  ```javascript
+  App = Ember.Application.create();
+  App.items = [
+    Ember.Object.create({name: 'Dave'}),
+    Ember.Object.create({name: 'Mary'}),
+    Ember.Object.create({name: 'Sara'})
+  ];
+
+  App.AnItemView = Ember.View.extend({
+    template: Ember.Handlebars.compile("Greetings {{view.content.name}}")
+  });
+  ```
+
+  Will result in the HTML structure below
+
+  ```html
+  <div class="ember-view">
+    <div class="ember-view">Greetings Dave</div>
+    <div class="ember-view">Greetings Mary</div>
+    <div class="ember-view">Greetings Sara</div>
+  </div>
+  ```
+
+  ### Specifying a CollectionView subclass
+
+  By default the `{{collection}}` helper will create an instance of
+  `Ember.CollectionView`. You can supply a `Ember.CollectionView` subclass to
+  the helper by passing it as the first argument:
+
+  ```handlebars
+  {{#collection App.MyCustomCollectionClass contentBinding="App.items"}}
+    Hi {{view.content.name}}
+  {{/collection}}
+  ```
+
+  ### Forwarded `item.*`-named Options
+
+  As with the `{{view}}`, helper options passed to the `{{collection}}` will be
+  set on the resulting `Ember.CollectionView` as properties. Additionally,
+  options prefixed with `item` will be applied to the views rendered for each
+  item (note the camelcasing):
+
+  ```handlebars
+  {{#collection contentBinding="App.items"
+                itemTagName="p"
+                itemClassNames="greeting"}}
+    Howdy {{view.content.name}}
+  {{/collection}}
+  ```
+
+  Will result in the following HTML structure:
+
+  ```html
+  <div class="ember-view">
+    <p class="ember-view greeting">Howdy Dave</p>
+    <p class="ember-view greeting">Howdy Mary</p>
+    <p class="ember-view greeting">Howdy Sara</p>
+  </div>
+  ```

+
+/**
+  The `{{#each}}` helper loops over elements in a collection, rendering its
+  block once for each item. It is an extension of the base Handlebars `{{#each}}`
+  helper:
+
+  ```javascript
+  Developers = [{name: 'Yehuda'},{name: 'Tom'}, {name: 'Paul'}];
+  ```
+
+  ```handlebars
+  {{#each Developers}}
+    {{name}}
+  {{/each}}
+  ```
+
+  `{{each}}` supports an alternative syntax with element naming:
+
+  ```handlebars
+  {{#each person in Developers}}
+    {{person.name}}
+  {{/each}}
+  ```
+
+  When looping over objects that do not have properties, `{{this}}` can be used
+  to render the object:
+
+  ```javascript
+  DeveloperNames = ['Yehuda', 'Tom', 'Paul']
+  ```
+
+  ```handlebars
+  {{#each DeveloperNames}}
+    {{this}}
+  {{/each}}
+  ```
+  ### {{else}} condition
+  `{{#each}}` can have a matching `{{else}}`. The contents of this block will render
+  if the collection is empty.
+
+  ```
+  {{#each person in Developers}}
+    {{person.name}}
+  {{else}}
+    <p>Sorry, nobody is available for this task.</p>
+  {{/each}}
+  ```
+  ### Specifying a View class for items
+  If you provide an `itemViewClass` option that references a view class
+  with its own `template` you can omit the block.
+
+  The following template:
+
+  ```handlebars
+  {{#view App.MyView }}
+    {{each view.items itemViewClass="App.AnItemView"}}
+  {{/view}}
+  ```
+
+  And application code
+
+  ```javascript
+  App = Ember.Application.create({
+    MyView: Ember.View.extend({
+      items: [
+        Ember.Object.create({name: 'Dave'}),
+        Ember.Object.create({name: 'Mary'}),
+        Ember.Object.create({name: 'Sara'})
+      ]
+    })
+  });
+
+  App.AnItemView = Ember.View.extend({
+    template: Ember.Handlebars.compile("Greetings {{name}}")
+  });
+  ```
+
+  Will result in the HTML structure below
+
+  ```html
+  <div class="ember-view">
+    <div class="ember-view">Greetings Dave</div>
+    <div class="ember-view">Greetings Mary</div>
+    <div class="ember-view">Greetings Sara</div>
+  </div>
+  ```
+
+  If an `itemViewClass` is defined on the helper, and therefore the helper is not
+  being used as a block, an `emptyViewClass` can also be provided optionally.
+  The `emptyViewClass` will match the behavior of the `{{else}}` condition
+  described above. That is, the `emptyViewClass` will render if the collection
+  is empty.
+
+  ### Representing each item with a Controller.
+  By default the controller lookup within an `{{#each}}` block will be
+  the controller of the template where the `{{#each}}` was used. If each
+  item needs to be presented by a custom controller you can provide a
+  `itemController` option which references a controller by lookup name.
+  Each item in the loop will be wrapped in an instance of this controller
+  and the item itself will be set to the `content` property of that controller.
+
+  This is useful in cases where properties of model objects need transformation
+  or synthesis for display:
+
+  ```javascript
+  App.DeveloperController = Ember.ObjectController.extend({
+    isAvailableForHire: function() {
+      return !this.get('content.isEmployed') && this.get('content.isSeekingWork');
+    }.property('isEmployed', 'isSeekingWork')
+  })
+  ```
+
+  ```handlebars
+  {{#each person in developers itemController="developer"}}
+    {{person.name}} {{#if person.isAvailableForHire}}Hire me!{{/if}}
+  {{/each}}
+  ```
+
+  Each itemController will receive a reference to the current controller as
+  a `parentController` property.
+
+  ### (Experimental) Grouped Each
+
+  When used in conjunction with the experimental [group helper](https://github.com/emberjs/group-helper),
+  you can inform Handlebars to re-render an entire group of items instead of
+  re-rendering them one at a time (in the event that they are changed en masse
+  or an item is added/removed).
+
+  ```handlebars
+  {{#group}}
+    {{#each people}}
+      {{firstName}} {{lastName}}
+    {{/each}}
+  {{/group}}
+  ```
+
+  This can be faster than the normal way that Handlebars re-renders items
+  in some cases.
+
+  If for some reason you have a group with more than one `#each`, you can make
+  one of the collections be updated in normal (non-grouped) fashion by setting
+  the option `groupedRows=true` (counter-intuitive, I know).
+
+  For example,
+
+  ```handlebars
+  {{dealershipName}}
+
+  {{#group}}
+    {{#each dealers}}
+      {{firstName}} {{lastName}}
+    {{/each}}
+
+    {{#each car in cars groupedRows=true}}
+      {{car.make}} {{car.model}} {{car.color}}
+    {{/each}}
+  {{/group}}
+  ```
+  Any change to `dealershipName` or the `dealers` collection will cause the
+  entire group to be re-rendered. However, changes to the `cars` collection
+  will be re-rendered individually (as normal).
+
+  Note that `group` behavior is also disabled by specifying an `itemViewClass`.

+  When used in a Handlebars template that is assigned to an `Ember.View`
+  instance's `layout` property Ember will render the layout template first,
+  inserting the view's own rendered output at the `{{yield}}` location.
+
+  An empty `<body>` and the following application code:
+

+  AView = Ember.View.extend({

+    layout: Ember.Handlebars.compile('<div class="wrapper">{{yield}}</div>'),

+      </div>
+    </div>
+  </body>
+  ```
+
+  The `yield` helper cannot be used outside of a template assigned to an
+  `Ember.View`'s `layout` property and will throw an error if attempted.
+
+  ```javascript

+  ### Use with Ember.Component
+  When designing components `{{yield}}` is used to denote where, inside the component's
+  template, an optional block passed to the component should render:
+
+  ```handlebars
+  <!-- application.hbs -->
+  {{#labeled-textfield value=someProperty}}
+    First name:

+/**
+  The `Ember.Select` view class renders a
+  [select](https://developer.mozilla.org/en/HTML/Element/select) HTML element,
+  allowing the user to choose from a list of options.
+
+  The text and `value` property of each `<option>` element within the
+  `<select>` element are populated from the objects in the `Element.Select`'s
+  `content` property. The underlying data object of the selected `<option>` is
+  stored in the `Element.Select`'s `value` property.
+
+  ## The Content Property (array of strings)
+
+  The simplest version of an `Ember.Select` takes an array of strings as its
+  `content` property. The string will be used as both the `value` property and
+  the inner text of each `<option>` element inside the rendered `<select>`.
+
+  Example:
+
+  ```javascript
+  App.ApplicationController = Ember.Controller.extend({
+    names: ["Yehuda", "Tom"]
+  });
+  ```
+
+  ```handlebars
+  {{view Ember.Select content=names}}
+  ```
+
+  Would result in the following HTML:
+
+  ```html
+  <select class="ember-select">
+    <option value="Yehuda">Yehuda</option>
+    <option value="Tom">Tom</option>
+  </select>
+  ```
+
+  You can control which `<option>` is selected through the `Ember.Select`'s
+  `value` property:
+
+  ```javascript
+  App.ApplicationController = Ember.Controller.extend({
+    selectedName: 'Tom',
+    names: ["Yehuda", "Tom"]
+  });
+  ```
+
+  ```handlebars
+  {{view Ember.Select
+         content=names
+         value=selectedName
+  }}
+  ```
+
+  Would result in the following HTML with the `<option>` for 'Tom' selected:
+
+  ```html
+  <select class="ember-select">
+    <option value="Yehuda">Yehuda</option>
+    <option value="Tom" selected="selected">Tom</option>
+  </select>
+  ```
+
+  A user interacting with the rendered `<select>` to choose "Yehuda" would
+  update the value of `selectedName` to "Yehuda".
+
+  ## The Content Property (array of Objects)
+
+  An `Ember.Select` can also take an array of JavaScript or Ember objects as
+  its `content` property.
+
+  When using objects you need to tell the `Ember.Select` which property should
+  be accessed on each object to supply the `value` attribute of the `<option>`
+  and which property should be used to supply the element text.
+
+  The `optionValuePath` option is used to specify the path on each object to
+  the desired property for the `value` attribute. The `optionLabelPath`
+  specifies the path on each object to the desired property for the
+  element's text. Both paths must reference each object itself as `content`:
+
+  ```javascript
+  App.ApplicationController = Ember.Controller.extend({
+    programmers: [
+      {firstName: "Yehuda", id: 1},
+      {firstName: "Tom",    id: 2}
+    ]
+  });
+  ```
+
+  ```handlebars
+  {{view Ember.Select
+         content=programmers
+         optionValuePath="content.id"
+         optionLabelPath="content.firstName"}}
+  ```
+
+  Would result in the following HTML:
+
+  ```html
+  <select class="ember-select">
+    <option value="1">Yehuda</option>
+    <option value="2">Tom</option>
+  </select>
+  ```
+
+  The `value` attribute of the selected `<option>` within an `Ember.Select`
+  can be bound to a property on another object:
+
+  ```javascript
+  App.ApplicationController = Ember.Controller.extend({
+    programmers: [
+      {firstName: "Yehuda", id: 1},
+      {firstName: "Tom",    id: 2}
+    ],
+    currentProgrammer: {
+      id: 2
+    }
+  });
+  ```
+
+  ```handlebars
+  {{view Ember.Select
+         content=programmers
+         optionValuePath="content.id"
+         optionLabelPath="content.firstName"
+         value=currentProgrammer.id}}
+  ```
+
+  Would result in the following HTML with a selected option:
+
+  ```html
+  <select class="ember-select">
+    <option value="1">Yehuda</option>
+    <option value="2" selected="selected">Tom</option>
+  </select>
+  ```
+
+  Interacting with the rendered element by selecting the first option
+  ('Yehuda') will update the `id` of `currentProgrammer`
+  to match the `value` property of the newly selected `<option>`.
+
+  Alternatively, you can control selection through the underlying objects
+  used to render each object by binding the `selection` option. When the selected
+  `<option>` is changed, the property path provided to `selection`
+  will be updated to match the content object of the rendered `<option>`
+  element:
+
+  ```javascript
+  App.ApplicationController = Ember.Controller.extend({
+    selectedPerson: null,
+    programmers: [
+      {firstName: "Yehuda", id: 1},
+      {firstName: "Tom",    id: 2}
+    ]
+  });
+  ```
+
+  ```handlebars
+  {{view Ember.Select
+         content=programmers
+         optionValuePath="content.id"
+         optionLabelPath="content.firstName"
+         selection=selectedPerson}}
+  ```
+
+  Would result in the following HTML with a selected option:
+
+  ```html
+  <select class="ember-select">
+    <option value="1">Yehuda</option>
+    <option value="2" selected="selected">Tom</option>
+  </select>
+  ```
+
+  Interacting with the rendered element by selecting the first option
+  ('Yehuda') will update the `selectedPerson` to match the object of
+  the newly selected `<option>`. In this case it is the first object
+  in the `programmers`
+
+  ## Supplying a Prompt
+
+  A `null` value for the `Ember.Select`'s `value` or `selection` property
+  results in there being no `<option>` with a `selected` attribute:
+
+  ```javascript
+  App.ApplicationController = Ember.Controller.extend({
+    selectedProgrammer: null,
+    programmers: [
+      "Yehuda",
+      "Tom"
+    ]
+  });
+  ```
+
+  ``` handlebars
+  {{view Ember.Select
+         content=programmers
+         value=selectedProgrammer
+  }}
+  ```
+
+  Would result in the following HTML:
+
+  ```html
+  <select class="ember-select">
+    <option value="Yehuda">Yehuda</option>
+    <option value="Tom">Tom</option>
+  </select>
+  ```
+
+  Although `selectedProgrammer` is `null` and no `<option>`
+  has a `selected` attribute the rendered HTML will display the
+  first item as though it were selected. You can supply a string
+  value for the `Ember.Select` to display when there is no selection
+  with the `prompt` option:
+
+  ```javascript
+  App.ApplicationController = Ember.Controller.extend({
+    selectedProgrammer: null,
+    programmers: [
+      "Yehuda",
+      "Tom"
+    ]
+  });
+  ```
+
+  ```handlebars
+  {{view Ember.Select
+         content=programmers
+         value=selectedProgrammer
+         prompt="Please select a name"
+  }}
+  ```
+
+  Would result in the following HTML:
+
+  ```html
+  <select class="ember-select">
+    <option>Please select a name</option>
+    <option value="Yehuda">Yehuda</option>
+    <option value="Tom">Tom</option>
+  </select>
+  ```

+/**
+
+  The `{{input}}` helper inserts an HTML `<input>` tag into the template,
+  with a `type` value of either `text` or `checkbox`. If no `type` is provided,
+  `text` will be the default value applied. The attributes of `{{input}}`
+  match those of the native HTML tag as closely as possible for these two types.
+
+  ## Use as text field
+  An `{{input}}` with no `type` or a `type` of `text` will render an HTML text input.
+  The following HTML attributes can be set via the helper:
+
+ <table>
+  <tr><td>`readonly`</td><td>`required`</td><td>`autofocus`</td></tr>
+  <tr><td>`value`</td><td>`placeholder`</td><td>`disabled`</td></tr>
+  <tr><td>`size`</td><td>`tabindex`</td><td>`maxlength`</td></tr>
+  <tr><td>`name`</td><td>`min`</td><td>`max`</td></tr>
+  <tr><td>`pattern`</td><td>`accept`</td><td>`autocomplete`</td></tr>
+  <tr><td>`autosave`</td><td>`formaction`</td><td>`formenctype`</td></tr>
+  <tr><td>`formmethod`</td><td>`formnovalidate`</td><td>`formtarget`</td></tr>
+  <tr><td>`height`</td><td>`inputmode`</td><td>`multiple`</td></tr>
+  <tr><td>`step`</td><td>`width`</td><td>`form`</td></tr>
+  <tr><td>`selectionDirection`</td><td>`spellcheck`</td><td> </td></tr>
+ </table>
+
+
+  When set to a quoted string, these values will be directly applied to the HTML
+  element. When left unquoted, these values will be bound to a property on the
+  template's current rendering context (most typically a controller instance).
+
+  ## Unbound:
+
+  ```handlebars
+  {{input value="http://www.facebook.com"}}
+  ```
+
+
+  ```html
+  <input type="text" value="http://www.facebook.com"/>
+  ```
+
+  ## Bound:
+
+  ```javascript
+  App.ApplicationController = Ember.Controller.extend({
+    firstName: "Stanley",
+    entryNotAllowed: true
+  });
+  ```
+
+
+  ```handlebars
+  {{input type="text" value=firstName disabled=entryNotAllowed size="50"}}
+  ```
+
+
+  ```html
+  <input type="text" value="Stanley" disabled="disabled" size="50"/>
+  ```
+
+  ## Extension
+
+  Internally, `{{input type="text"}}` creates an instance of `Ember.TextField`, passing
+  arguments from the helper to `Ember.TextField`'s `create` method. You can extend the
+  capablilties of text inputs in your applications by reopening this class. For example,
+  if you are deploying to browsers where the `required` attribute is used, you
+  can add this to the `TextField`'s `attributeBindings` property:
+
+
+  ```javascript
+  Ember.TextField.reopen({
+    attributeBindings: ['required']
+  });
+  ```
+
+  Keep in mind when writing `Ember.TextField` subclasses that `Ember.TextField`
+  itself extends `Ember.Component`, meaning that it does NOT inherit
+  the `controller` of the parent view.
+
+  See more about [Ember components](api/classes/Ember.Component.html)
+
+
+  ## Use as checkbox
+
+  An `{{input}}` with a `type` of `checkbox` will render an HTML checkbox input.
+  The following HTML attributes can be set via the helper:
+
+* `checked`
+* `disabled`
+* `tabindex`
+* `indeterminate`
+* `name`
+* `autofocus`
+* `form`
+
+
+  When set to a quoted string, these values will be directly applied to the HTML
+  element. When left unquoted, these values will be bound to a property on the
+  template's current rendering context (most typically a controller instance).
+
+  ## Unbound:
+
+  ```handlebars
+  {{input type="checkbox" name="isAdmin"}}
+  ```
+
+  ```html
+  <input type="checkbox" name="isAdmin" />
+  ```
+
+  ## Bound:
+
+  ```javascript
+  App.ApplicationController = Ember.Controller.extend({
+    isAdmin: true
+  });
+  ```
+
+
+  ```handlebars
+  {{input type="checkbox" checked=isAdmin }}
+  ```
+
+
+  ```html
+  <input type="checkbox" checked="checked" />
+  ```
+
+  ## Extension
+
+  Internally, `{{input type="checkbox"}}` creates an instance of `Ember.Checkbox`, passing
+  arguments from the helper to `Ember.Checkbox`'s `create` method. You can extend the
+  capablilties of checkbox inputs in your applications by reopening this class. For example,
+  if you wanted to add a css class to all checkboxes in your application:
+
+
+  ```javascript
+  Ember.Checkbox.reopen({
+    classNames: ['my-app-checkbox']
+  });

+    return Ember.Handlebars.helpers.view.call(this, Ember.Checkbox, options);
+  } else {

+
+/**
+  `{{textarea}}` inserts a new instance of `<textarea>` tag into the template.
+  The attributes of `{{textarea}}` match those of the native HTML tags as
+  closely as possible.
+
+  The following HTML attributes can be set:
+
+    * `value`
+    * `name`
+    * `rows`
+    * `cols`
+    * `placeholder`
+    * `disabled`
+    * `maxlength`
+    * `tabindex`
+    * `selectionEnd`
+    * `selectionStart`
+    * `selectionDirection`
+    * `wrap`
+    * `readonly`
+    * `autofocus`
+    * `form`
+    * `spellcheck`
+    * `required`
+
+  When set to a quoted string, these value will be directly applied to the HTML
+  element. When left unquoted, these values will be bound to a property on the
+  template's current rendering context (most typically a controller instance).
+
+  Unbound:
+
+  ```handlebars
+  {{textarea value="Lots of static text that ISN'T bound"}}
+  ```
+
+  Would result in the following HTML:
+
+  ```html
+  <textarea class="ember-text-area">
+    Lots of static text that ISN'T bound
+  </textarea>
+  ```
+
+  Bound:
+
+  In the following example, the `writtenWords` property on `App.ApplicationController`
+  will be updated live as the user types 'Lots of text that IS bound' into
+  the text area of their browser's window.
+
+  ```javascript
+  App.ApplicationController = Ember.Controller.extend({
+    writtenWords: "Lots of text that IS bound"
+  });
+  ```
+
+  ```handlebars
+  {{textarea value=writtenWords}}
+  ```
+
+   Would result in the following HTML:
+
+  ```html
+  <textarea class="ember-text-area">
+    Lots of text that IS bound
+  </textarea>
+  ```
+
+  If you wanted a one way binding between the text area and a div tag
+  somewhere else on your screen, you could use `Ember.computed.oneWay`:
+
+  ```javascript
+  App.ApplicationController = Ember.Controller.extend({
+    writtenWords: "Lots of text that IS bound",
+    outputWrittenWords: Ember.computed.oneWay("writtenWords")
+  });
+  ```
+
+  ```handlebars
+  {{textarea value=writtenWords}}
+
+  <div>
+    {{outputWrittenWords}}
+  </div>
+  ```
+
+  Would result in the following HTML:
+
+  ```html
+  <textarea class="ember-text-area">
+    Lots of text that IS bound
+  </textarea>
+
+  <-- the following div will be updated in real time as you type -->
+
+  <div>
+    Lots of text that IS bound
+  </div>
+  ```
+
+  Finally, this example really shows the power and ease of Ember when two
+  properties are bound to eachother via `Ember.computed.alias`. Type into
+  either text area box and they'll both stay in sync. Note that
+  `Ember.computed.alias` costs more in terms of performance, so only use it when
+  your really binding in both directions:
+
+  ```javascript
+  App.ApplicationController = Ember.Controller.extend({
+    writtenWords: "Lots of text that IS bound",
+    twoWayWrittenWords: Ember.computed.alias("writtenWords")
+  });
+  ```
+
+  ```handlebars
+  {{textarea value=writtenWords}}
+  {{textarea value=twoWayWrittenWords}}
+  ```
+
+  ```html
+  <textarea id="ember1" class="ember-text-area">
+    Lots of text that IS bound
+  </textarea>
+
+  <-- both updated in real time -->
+
+  <textarea id="ember2" class="ember-text-area">
+    Lots of text that IS bound
+  </textarea>
+  ```
+
+  ## Extension
+
+  Internally, `{{textarea}}` creates an instance of `Ember.TextArea`, passing
+  arguments from the helper to `Ember.TextArea`'s `create` method. You can
+  extend the capabilities of text areas in your application by reopening this
+  class. For example, if you are deploying to browsers where the `required`
+  attribute is used, you can globally add support for the `required` attribute
+  on all `{{textarea}}`s' in your app by reopening `Ember.TextArea` or
+  `Ember.TextSupport` and adding it to the `attributeBindings` concatenated
+  property:
+
+  ```javascript
+  Ember.TextArea.reopen({
+    attributeBindings: ['required']
+  });
+  ```
+
+  Keep in mind when writing `Ember.TextArea` subclasses that `Ember.TextArea`

+    The name of the controller to associate with this route.
+
+    By default, Ember will lookup a route's controller that matches the name
+    of the route (i.e. `App.PostController` for `App.PostRoute`). However,
+    if you would like to define a specific controller to use, you can do so
+    using this property.
+
+    This is useful in many ways, as the controller specified will be:
+
+    * passed to the `setupController` method.
+    * used as the controller for the view being rendered by the route.
+    * returned from a call to `controllerFor` for the route.
+
+    @property controllerName
+    @type String
+    @default null
+  */
+  controllerName: null,
+
+  /**
+    The collection of functions, keyed by name, available on this route as
+    action targets.
+
+    These functions will be invoked when a matching `{{action}}` is triggered
+    from within a template and the application's current route is this route.
+
+    Actions can also be invoked from other parts of your application via `Route#send`
+    or `Controller#send`.
+
+    The `actions` hash will inherit action handlers from
+    the `actions` hash defined on extended Route parent classes
+    or mixins rather than just replace the entire hash, e.g.:
+
+    ```js
+    App.CanDisplayBanner = Ember.Mixin.create({
+      actions: {
+        displayBanner: function(msg) {
+          // ...
+        }
+      }
+    });
+
+    App.WelcomeRoute = Ember.Route.extend(App.CanDisplayBanner, {
+      actions: {
+        playMusic: function() {
+          // ...
+        }
+      }
+    });
+
+    // `WelcomeRoute`, when active, will be able to respond
+    // to both actions, since the actions hash is merged rather
+    // then replaced when extending mixins / parent classes.
+    this.send('displayBanner');
+    this.send('playMusic');
+    ```
+
+    Within a route's action handler, the value of the `this` context
+    is the Route object:
+
+    ```js
+    App.SongRoute = Ember.Route.extend({
+      actions: {
+        myAction: function() {
+          this.controllerFor("song");
+          this.transitionTo("other.route");
+          ...
+        }
+      }
+    });
+    ```
+
+    It is also possible to call `this._super()` from within an
+    action handler if it overrides a handler defined on a parent
+    class or mixin:
+
+    Take for example the following routes:
+
+    ```js
+    App.DebugRoute = Ember.Mixin.create({
+      actions: {
+        debugRouteInformation: function() {
+          console.debug("trololo");
+        }
+      }
+    });
+
+    App.AnnoyingDebugRoute = Ember.Route.extend(App.DebugRoute, {
+      actions: {
+        debugRouteInformation: function() {
+          // also call the debugRouteInformation of mixed in App.DebugRoute
+          this._super();
+
+          // show additional annoyance
+          window.alert(...);
+        }
+      }
+    });
+    ```
+
+    ## Bubbling
+
+    By default, an action will stop bubbling once a handler defined
+    on the `actions` hash handles it. To continue bubbling the action,
+    you must return `true` from the handler:
+
+    ```js
+    App.Router.map(function() {
+      this.resource("album", function() {
+        this.route("song");
+      });
+    });
+
+    App.AlbumRoute = Ember.Route.extend({
+      actions: {
+        startPlaying: function() {
+        }
+      }
+    });
+
+    App.AlbumSongRoute = Ember.Route.extend({
+      actions: {
+        startPlaying: function() {
+          // ...
+
+          if (actionShouldAlsoBeTriggeredOnParentRoute) {
+            return true;
+          }
+        }
+      }
+    });
+    ```
+
+    ## Built-in actions
+
+    There are a few built-in actions pertaining to transitions that you
+    can use to customize transition behavior: `willTransition` and
+    `error`.
+
+    ### `willTransition`
+
+    The `willTransition` action is fired at the beginning of any
+    attempted transition with a `Transition` object as the sole
+    argument. This action can be used for aborting, redirecting,
+    or decorating the transition from the currently active routes.
+
+    A good example is preventing navigation when a form is
+    half-filled out:
+
+    ```js
+    App.ContactFormRoute = Ember.Route.extend({
+      actions: {
+        willTransition: function(transition) {
+          if (this.controller.get('userHasEnteredData')) {
+            this.controller.displayNavigationConfirm();
+            transition.abort();
+          }
+        }
+      }
+    });
+    ```
+
+    You can also redirect elsewhere by calling
+    `this.transitionTo('elsewhere')` from within `willTransition`.
+    Note that `willTransition` will not be fired for the
+    redirecting `transitionTo`, since `willTransition` doesn't
+    fire when there is already a transition underway. If you want
+    subsequent `willTransition` actions to fire for the redirecting
+    transition, you must first explicitly call
+    `transition.abort()`.
+
+    ### `error`
+
+    When attempting to transition into a route, any of the hooks
+    may return a promise that rejects, at which point an `error`
+    action will be fired on the partially-entered routes, allowing
+    for per-route error handling logic, or shared error handling
+    logic defined on a parent route.
+
+    Here is an example of an error handler that will be invoked
+    for rejected promises from the various hooks on the route,
+    as well as any unhandled errors from child routes:
+
+    ```js
+    App.AdminRoute = Ember.Route.extend({
+      beforeModel: function() {
+        return Ember.RSVP.reject("bad things!");
+      },
+
+      actions: {
+        error: function(error, transition) {
+          // Assuming we got here due to the error in `beforeModel`,
+          // we can expect that error === "bad things!",
+          // but a promise model rejecting would also
+          // call this hook, as would any errors encountered
+          // in `afterModel`.
+
+          // The `error` hook is also provided the failed
+          // `transition`, which can be stored and later
+          // `.retry()`d if desired.
+
+          this.transitionTo('login');
+        }
+      }
+    });
+    ```
+
+    `error` actions that bubble up all the way to `ApplicationRoute`
+    will fire a default error handler that logs the error. You can
+    specify your own global default error handler by overriding the
+    `error` handler on `ApplicationRoute`:
+
+    ```js
+    App.ApplicationRoute = Ember.Route.extend({
+      actions: {
+        error: function(error, transition) {
+          this.controllerFor('banner').displayError(error.message);
+        }
+      }
+    });
+    ```
+
+    @property actions
+    @type Hash
+    @default null
+  */
+  _actions: {
+    finalizeQueryParamChange: function(params, finalParams) {
+          }
+  },
+
+  /**
+    @deprecated
+
+    Please use `actions` instead.
+    @method events
+  */
+  events: null,
+
+  mergedProperties: ['events'],
+
+  /**
+    This hook is executed when the router completely exits this route. It is
+    not executed when the model for the route changes.
+
+    @method deactivate
+  */
+  deactivate: Ember.K,
+
+  /**
+    This hook is executed when the router enters the route. It is not executed
+    when the model for the route changes.
+
+    @method activate
+  */
+  activate: Ember.K,
+
+  /**
+    Transition the application into another route. The route may
+    be either a single route or route path:
+
+    ```javascript
+    this.transitionTo('blogPosts');
+    this.transitionTo('blogPosts.recentEntries');
+    ```
+
+    Optionally supply a model for the route in question. The model
+    will be serialized into the URL using the `serialize` hook of
+    the route:
+
+    ```javascript
+    this.transitionTo('blogPost', aPost);
+    ```
+
+    If a literal is passed (such as a number or a string), it will
+    be treated as an identifier instead. In this case, the `model`
+    hook of the route will be triggered:
+
+    ```javascript
+    this.transitionTo('blogPost', 1);
+    ```
+
+    Multiple models will be applied last to first recursively up the
+    resource tree.
+
+    ```javascript
+    App.Router.map(function() {
+      this.resource('blogPost', {path:':blogPostId'}, function(){
+        this.resource('blogComment', {path: ':blogCommentId'});
+      });
+    });
+    
+    this.transitionTo('blogComment', aPost, aComment);
+    this.transitionTo('blogComment', 1, 13);
+    ```
+
+    It is also possible to pass a URL (a string that starts with a
+    `/`). This is intended for testing and debugging purposes and
+    should rarely be used in production code.
+
+    ```javascript
+    this.transitionTo('/');
+    this.transitionTo('/blog/post/1/comment/13');
+    ```
+
+    See also 'replaceWith'.
+
+    Simple Transition Example
+
+    ```javascript
+    App.Router.map(function() {
+      this.route("index");
+      this.route("secret");
+      this.route("fourOhFour", { path: "*:"});
+    });
+
+    App.IndexRoute = Ember.Route.extend({

+          }
+            this.transitionTo('fourOhFour');
+        }
+      }
+    });
+    ```
+
+    Transition to a nested route
+
+    ```javascript
+    App.Router.map(function() {
+      this.resource('articles', { path: '/articles' }, function() {

+
+    1) A decision can be made to redirect elsewhere without
+       needing to resolve the model first.
+    2) Any async operations need to occur first before the
+       model is attempted to be resolved.
+
+    This hook is provided the current `transition` attempt
+    as a parameter, which can be used to `.abort()` the transition,
+    save it for a later `.retry()`, or retrieve values set
+    on it from a previous hook. You can also just call
+    `this.transitionTo` to another route to implicitly
+    abort the `transition`.
+
+    You can return a promise from this hook to pause the
+    transition until the promise resolves (or rejects). This could
+    be useful, for instance, for retrieving async code from
+    the server that is required to enter a route.
+
+    ```js

+
+    If `App.Post` doesn't exist in the above example,
+    `beforeModel` will use jQuery's `getScript`, which
+    returns a promise that resolves after the server has
+    successfully retrieved and executed the code from the
+    server. Note that if an error were to occur, it would
+    be passed to the `error` hook on `Ember.Route`, but
+    it's also possible to handle errors specific to

+
+    ```js
+    App.Router.map(function() {
+      this.resource('post', {path: '/posts/:post_id'});
+    });
+    ```
+
+    The model for the `post` route is `App.Post.find(params.post_id)`.
+
+    By default, if your route has a dynamic segment ending in `_id`:
+
+    * The model class is determined from the segment (`post_id`'s
+      class is `App.Post`)
+    * The find method is called on the model class with the value of
+      the dynamic segment.
+
+    Note that for routes with dynamic segments, this hook is only
+    executed when entered via the URL. If the route is entered
+    through a transition (e.g. when using the `link-to` Handlebars
+    helper), then a model context is already provided and this hook
+    is not called. Routes without dynamic segments will always
+    execute the model hook.
+
+    This hook follows the asynchronous/promise semantics
+    described in the documentation for `beforeModel`. In particular,
+    if a promise returned from `model` fails, the error will be
+    handled by the `error` hook on `Ember.Route`.
+
+    Example
+
+    ```js
+    App.PostRoute = Ember.Route.extend({
+      model: function(params) {
+        return App.Post.find(params.post_id);
+      }

+    @method model

+    @param {Transition} transition
+    @param {Object} queryParams the query params for this route
+    @return {Object|Promise} the model for this route. If
+      a promise is returned, the transition will pause until
+      the promise resolves, and the resolved value of the promise
+      will be used as the model for this route.

+    A hook you can use to setup the controller for the current route.
+
+    This method is called with the controller for the current route and the
+    model supplied by the `model` hook.
+
+    By default, the `setupController` hook sets the `content` property of
+    the controller to the `model`.
+
+    If you implement the `setupController` hook in your Route, it will
+    prevent this default behavior. If you want to preserve that behavior
+    when implementing your `setupController` function, make sure to call
+    `_super`:
+
+    ```js
+    App.PhotosRoute = Ember.Route.extend({
+      model: function() {
+        return App.Photo.find();
+      },
+
+      setupController: function (controller, model) {
+        // Call _super for default behavior
+        this._super(controller, model);
+        // Implement your custom setup after
+        this.controllerFor('application').set('showingPhotos', true);
+      }
+    });
+    ```
+
+    This means that your template will get a proxy for the model as its
+    context, and you can act as though the model itself was the context.
+
+    The provided controller will be one resolved based on the name
+    of this route.
+
+    If no explicit controller is defined, Ember will automatically create
+    an appropriate controller for the model.
+
+    * if the model is an `Ember.Array` (including record arrays from Ember
+      Data), the controller is an `Ember.ArrayController`.
+    * otherwise, the controller is an `Ember.ObjectController`.
+
+    As an example, consider the router:
+
+    ```js
+    App.Router.map(function() {
+      this.resource('post', {path: '/posts/:post_id'});
+    });
+    ```
+
+    For the `post` route, a controller named `App.PostController` would
+    be used if it is defined. If it is not defined, an `Ember.ObjectController`
+    instance would be used.
+
+    Example
+
+    ```js
+    App.PostRoute = Ember.Route.extend({
+      setupController: function(controller, model) {
+        controller.set('model', model);

+    The `{{link-to}}` helper renders a link to the supplied
+    `routeName` passing an optionally supplied model to the
+    route as its `model` context of the route. The block
+    for `{{link-to}}` becomes the innerHTML of the rendered
+    element:
+
+    ```handlebars
+    {{#link-to 'photoGallery'}}
+      Great Hamster Photos
+    {{/link-to}}
+    ```
+
+    ```html
+    <a href="/hamster-photos">
+      Great Hamster Photos
+    </a>
+    ```
+
+    ### Supplying a tagName
+    By default `{{link-to}}` renders an `<a>` element. This can
+    be overridden for a single use of `{{link-to}}` by supplying
+    a `tagName` option:
+
+    ```handlebars
+    {{#link-to 'photoGallery' tagName="li"}}
+      Great Hamster Photos
+    {{/link-to}}
+    ```
+
+    ```html
+    <li>
+      Great Hamster Photos
+    </li>
+    ```
+
+    To override this option for your entire application, see
+    "Overriding Application-wide Defaults".
+
+    ### Disabling the `link-to` helper
+    By default `{{link-to}}` is enabled.
+    any passed value to `disabled` helper property will disable the `link-to` helper.
+
+    static use: the `disabled` option:
+
+    ```handlebars
+    {{#link-to 'photoGallery' disabled=true}}
+      Great Hamster Photos
+    {{/link-to}}
+    ```
+
+    dynamic use: the `disabledWhen` option:
+
+    ```handlebars
+    {{#link-to 'photoGallery' disabledWhen=controller.someProperty}}
+      Great Hamster Photos
+    {{/link-to}}
+    ```
+
+    any passed value to `disabled` will disable it except `undefined`.
+    to ensure that only `true` disable the `link-to` helper you can
+    override the global behaviour of `Ember.LinkView`.
+
+    ```javascript
+    Ember.LinkView.reopen({
+      disabled: Ember.computed(function(key, value) {
+        if (value !== undefined) {
+          this.set('_isDisabled', value === true);
+        }
+        return value === true ? get(this, 'disabledClass') : false;
+      })
+    });
+    ```
+
+    see "Overriding Application-wide Defaults" for more.
+
+    ### Handling `href`
+    `{{link-to}}` will use your application's Router to
+    fill the element's `href` property with a url that
+    matches the path to the supplied `routeName` for your
+    routers's configured `Location` scheme, which defaults
+    to Ember.HashLocation.
+
+    ### Handling current route
+    `{{link-to}}` will apply a CSS class name of 'active'
+    when the application's current route matches
+    the supplied routeName. For example, if the application's
+    current route is 'photoGallery.recent' the following
+    use of `{{link-to}}`:
+
+    ```handlebars
+    {{#link-to 'photoGallery.recent'}}
+      Great Hamster Photos from the last week
+    {{/link-to}}
+    ```
+
+    will result in
+
+    ```html
+    <a href="/hamster-photos/this-week" class="active">
+      Great Hamster Photos
+    </a>
+    ```
+
+    The CSS class name used for active classes can be customized
+    for a single use of `{{link-to}}` by passing an `activeClass`
+    option:
+
+    ```handlebars
+    {{#link-to 'photoGallery.recent' activeClass="current-url"}}
+      Great Hamster Photos from the last week
+    {{/link-to}}
+    ```
+
+    ```html
+    <a href="/hamster-photos/this-week" class="current-url">
+      Great Hamster Photos
+    </a>
+    ```
+
+    To override this option for your entire application, see
+    "Overriding Application-wide Defaults".
+
+    ### Supplying a model
+    An optional model argument can be used for routes whose
+    paths contain dynamic segments. This argument will become
+    the model context of the linked route:
+
+    ```javascript
+    App.Router.map(function() {
+      this.resource("photoGallery", {path: "hamster-photos/:photo_id"});
+    });
+    ```
+
+    ```handlebars
+    {{#link-to 'photoGallery' aPhoto}}
+      {{aPhoto.title}}
+    {{/link-to}}
+    ```
+
+    ```html
+    <a href="/hamster-photos/42">
+      Tomster
+    </a>
+    ```
+
+    ### Supplying multiple models
+    For deep-linking to route paths that contain multiple
+    dynamic segments, multiple model arguments can be used.
+    As the router transitions through the route path, each
+    supplied model argument will become the context for the
+    route with the dynamic segments:
+
+    ```javascript
+    App.Router.map(function() {
+      this.resource("photoGallery", {path: "hamster-photos/:photo_id"}, function() {
+        this.route("comment", {path: "comments/:comment_id"});
+      });
+    });
+    ```
+    This argument will become the model context of the linked route:
+
+    ```handlebars
+    {{#link-to 'photoGallery.comment' aPhoto comment}}
+      {{comment.body}}
+    {{/link-to}}
+    ```
+
+    ```html
+    <a href="/hamster-photos/42/comment/718">
+      A+++ would snuggle again.
+    </a>
+    ```
+
+    ### Supplying an explicit dynamic segment value
+    If you don't have a model object available to pass to `{{link-to}}`,
+    an optional string or integer argument can be passed for routes whose
+    paths contain dynamic segments. This argument will become the value
+    of the dynamic segment:
+
+    ```javascript
+    App.Router.map(function() {
+      this.resource("photoGallery", {path: "hamster-photos/:photo_id"});
+    });
+    ```
+
+    ```handlebars
+    {{#link-to 'photoGallery' aPhotoId}}
+      {{aPhoto.title}}
+    {{/link-to}}
+    ```
+
+    ```html
+    <a href="/hamster-photos/42">
+      Tomster
+    </a>
+    ```
+
+    When transitioning into the linked route, the `model` hook will
+    be triggered with parameters including this passed identifier.
+
+    ### Allowing Default Action
+
+   By default the `{{link-to}}` helper prevents the default browser action
+   by calling `preventDefault()` as this sort of action bubbling is normally
+   handled internally and we do not want to take the browser to a new URL (for
+   example).
+
+   If you need to override this behavior specify `preventDefault=false` in
+   your template:
+
+    ```handlebars
+    {{#link-to 'photoGallery' aPhotoId preventDefault=false}}
+      {{aPhotoId.title}}
+    {{/link-to}}
+    ```
+
+    ### Overriding attributes
+    You can override any given property of the Ember.LinkView
+    that is generated by the `{{link-to}}` helper by passing
+    key/value pairs, like so:
+
+    ```handlebars
+    {{#link-to  aPhoto tagName='li' title='Following this link will change your life' classNames='pic sweet'}}
+      Uh-mazing!
+    {{/link-to}}
+    ```
+
+    See [Ember.LinkView](/api/classes/Ember.LinkView.html) for a
+    complete list of overrideable properties. Be sure to also
+    check out inherited properties of `LinkView`.
+
+    ### Overriding Application-wide Defaults
+    ``{{link-to}}`` creates an instance of Ember.LinkView
+    for rendering. To override options for your entire
+    application, reopen Ember.LinkView and supply the
+    desired values:
+
+    ``` javascript
+    Ember.LinkView.reopen({
+      activeClass: "is-active",
+      tagName: 'li'
+    })
+    ```
+
+    It is also possible to override the default event in
+    this manner:
+
+    ``` javascript
+    Ember.LinkView.reopen({
+      eventName: 'customEventName'
+    });
+    ```
+
+    @method link-to
+    @for Ember.Handlebars.helpers
+    @param {String} routeName
+    @param {Object} [context]*
+    @param [options] {Object} Handlebars key/value pairs of options, you can override any property of Ember.LinkView
+    @return {String} HTML string
+    @see {Ember.LinkView}
+  */

+    the appropriate template based on the current state of the application.
+
+    ``` handlebars
+    {{outlet}}
+    ```
+
+    By default, a template based on Ember's naming conventions will be rendered
+    into the `outlet` (e.g. `App.PostsRoute` will render the `posts` template).
+
+    You can render a different template by using the `render()` method in the
+    route's `renderTemplate` hook. The following will render the `favoritePost`
+    template into the `outlet`.
+
+    ``` javascript
+    App.PostsRoute = Ember.Route.extend({
+      renderTemplate: function() {
+        this.render('favoritePost');
+      }
+    });
+    ```
+
+    You can create custom named outlets for more control.
+
+    ``` handlebars
+    {{outlet 'favoritePost'}}
+    {{outlet 'posts'}}
+    ```
+
+    Then you can define what template is rendered into each outlet in your
+    route.
+
+
+    ``` javascript
+    App.PostsRoute = Ember.Route.extend({
+      renderTemplate: function() {
+        this.render('favoritePost', { outlet: 'favoritePost' });
+        this.render('posts', { outlet: 'posts' });
+      }
+    });
+    ```
+
+    You can specify the view that the outlet uses to contain and manage the
+    templates rendered into it.
+
+    ``` handlebars
+    {{outlet view='sectionContainer'}}
+    ```
+
+    ``` javascript

+
+    If a view class with the same name exists, the view class also will be used.
+
+    Note: A given controller may only be used *once* in your app in this manner.
+    A singleton instance of the controller will be created for you.
+
+    Example:

+    });
+    ```

+  /**
+    The `{{action}}` helper registers an HTML element within a template for DOM
+    event handling and forwards that interaction to the templates's controller
+    or supplied `target` option (see 'Specifying a Target').
+
+    If the controller does not implement the event, the event is sent
+    to the current route, and it bubbles up the route hierarchy from there.
+
+    User interaction with that element will invoke the supplied action name on
+    the appropriate target. Specifying a non-quoted action name will result in
+    a bound property lookup at the time the event will be triggered.
+
+    Given the following application Handlebars template on the page
+
+    ```handlebars
+    <div {{action 'anActionName'}}>
+      click me
+    </div>
+    ```
+
+    And application code
+
+    ```javascript
+    App.ApplicationController = Ember.Controller.extend({
+      actions: {
+        anActionName: function() {
+        }
+      }
+    });
+    ```
+
+    Will result in the following rendered HTML
+
+    ```html
+    <div class="ember-view">
+      <div data-ember-action="1">
+        click me
+      </div>
+    </div>
+    ```
+
+    Clicking "click me" will trigger the `anActionName` action of the
+    `App.ApplicationController`. In this case, no additional parameters will be passed.
+
+    If you provide additional parameters to the helper:
+
+    ```handlebars
+    <button {{action 'edit' post}}>Edit</button>
+    ```
+
+    Those parameters will be passed along as arguments to the JavaScript
+    function implementing the action.
+
+    ### Event Propagation
+
+    Events triggered through the action helper will automatically have
+    `.preventDefault()` called on them. You do not need to do so in your event
+    handlers. If you need to allow event propagation (to handle file inputs for
+    example) you can supply the `preventDefault=false` option to the `{{action}}` helper:
+
+    ```handlebars
+    <div {{action "sayHello" preventDefault=false}}>
+      <input type="file" />
+      <input type="checkbox" />
+    </div>
+    ```
+
+    To disable bubbling, pass `bubbles=false` to the helper:
+
+    ```handlebars
+    <button {{action 'edit' post bubbles=false}}>Edit</button>
+    ```
+
+    If you need the default handler to trigger you should either register your
+    own event handler, or use event methods on your view class. See [Ember.View](/api/classes/Ember.View.html)
+    'Responding to Browser Events' for more information.
+
+    ### Specifying DOM event type
+
+    By default the `{{action}}` helper registers for DOM `click` events. You can
+    supply an `on` option to the helper to specify a different DOM event name:
+
+    ```handlebars
+    <div {{action "anActionName" on="doubleClick"}}>
+      click me
+    </div>
+    ```
+
+    See `Ember.View` 'Responding to Browser Events' for a list of
+    acceptable DOM event names.
+
+    NOTE: Because `{{action}}` depends on Ember's event dispatch system it will
+    only function if an `Ember.EventDispatcher` instance is available. An
+    `Ember.EventDispatcher` instance will be created when a new `Ember.Application`
+    is created. Having an instance of `Ember.Application` will satisfy this
+    requirement.
+
+    ### Specifying whitelisted modifier keys
+
+    By default the `{{action}}` helper will ignore click event with pressed modifier
+    keys. You can supply an `allowedKeys` option to specify which keys should not be ignored.
+
+    ```handlebars
+    <div {{action "anActionName" allowedKeys="alt"}}>
+      click me
+    </div>
+    ```
+
+    This way the `{{action}}` will fire when clicking with the alt key pressed down.
+
+    Alternatively, supply "any" to the `allowedKeys` option to accept any combination of modifier keys.
+
+    ```handlebars
+    <div {{action "anActionName" allowedKeys="any"}}>
+      click me with any key pressed
+    </div>
+    ```
+
+    ### Specifying a Target
+
+    There are several possible target objects for `{{action}}` helpers:
+
+    In a typical Ember application, where views are managed through use of the
+    `{{outlet}}` helper, actions will bubble to the current controller, then
+    to the current route, and then up the route hierarchy.
+
+    Alternatively, a `target` option can be provided to the helper to change
+    which object will receive the method call. This option must be a path
+    to an object, accessible in the current context:
+
+    ```handlebars
+    {{! the application template }}
+    <div {{action "anActionName" target=view}}>
+      click me
+    </div>
+    ```
+
+    ```javascript
+    App.ApplicationView = Ember.View.extend({
+      actions: {
+        anActionName: function(){}
+      }
+    });
+
+    ```
+
+    ### Additional Parameters
+
+    You may specify additional parameters to the `{{action}}` helper. These
+    parameters are passed along as the arguments to the JavaScript function
+    implementing the action.
+
+    ```handlebars
+    {{#each person in people}}
+      <div {{action "edit" person}}>
+        click me
+      </div>
+    {{/each}}
+    ```
+
+    Clicking "click me" will trigger the `edit` method on the current controller
+    with the value of `person` as a parameter.
+
+    @method action
+    @for Ember.Handlebars.helpers
+    @param {String} actionName
+    @param {Object} [context]*

+  Ember.Location returns an instance of the correct implementation of
+  the `location` API.
+
+  ## Implementations
+
+  You can pass an implementation name (`hash`, `history`, `none`) to force a
+  particular implementation to be used in your application.
+
+  ### HashLocation
+
+  Using `HashLocation` results in URLs with a `#` (hash sign) separating the
+  server side URL portion of the URL from the portion that is used by Ember.
+  This relies upon the `hashchange` event existing in the browser.
+
+  Example:
+
+  ```javascript
+  App.Router.map(function() {
+    this.resource('posts', function() {
+      this.route('new');
+    });
+  });
+
+  App.Router.reopen({
+    location: 'hash'
+  });
+  ```
+
+  This will result in a posts.new url of `/#/posts/new`.
+
+  ### HistoryLocation
+
+  Using `HistoryLocation` results in URLs that are indistinguishable from a
+  standard URL. This relies upon the browser's `history` API.
+
+  Example:
+
+  ```javascript
+  App.Router.map(function() {
+    this.resource('posts', function() {
+      this.route('new');
+    });
+  });
+
+  App.Router.reopen({
+    location: 'history'
+  });
+  ```
+
+  This will result in a posts.new url of `/posts/new`.
+
+  Keep in mind that your server must serve the Ember app at all the routes you
+  define.
+
+  ### AutoLocation
+
+  Using `AutoLocation`, the router will use the best Location class supported by
+  the browser it is running in.
+
+  Browsers that support the `history` API will use `HistoryLocation`, those that
+  do not, but still support the `hashchange` event will use `HashLocation`, and
+  in the rare case neither is supported will use `NoneLocation`.
+
+  Example:
+
+  ```javascript
+  App.Router.map(function() {
+    this.resource('posts', function() {
+      this.route('new');
+    });
+  });
+
+  App.Router.reopen({
+    location: 'auto'
+  });
+  ```
+
+  This will result in a posts.new url of `/posts/new` for modern browsers that
+  support the `history` api or `/#/posts/new` for older ones, like Internet
+  Explorer 9 and below.
+
+  When a user visits a link to your application, they will be automatically
+  upgraded or downgraded to the appropriate `Location` class, with the URL
+  transformed accordingly, if needed.
+
+  Keep in mind that since some of your users will use `HistoryLocation`, your
+  server must serve the Ember app at all the routes you define.
+
+  ### NoneLocation
+
+  Using `NoneLocation` causes Ember to not store the applications URL state
+  in the actual URL. This is generally used for testing purposes, and is one
+  of the changes made when calling `App.setupForTesting()`.
+
+  ## Location API
+
+  Each location implementation must provide the following methods:
+

+/**
+  The DefaultResolver defines the default lookup rules to resolve

+  items:
+
+  * templates are looked up on `Ember.TEMPLATES`
+  * other names are looked up on the application after converting
+    the name. For example, `controller:post` looks up
+    `App.PostController` by default.
+  * there are some nuances (see examples below)
+
+  ### How Resolving Works
+
+  The container calls this object's `resolve` method with the
+  `fullName` argument.
+
+  It first parses the fullName into an object using `parseName`.
+
+  Then it checks for the presence of a type-specific instance
+  method of the form `resolve[Type]` and calls it if it exists.
+  For example if it was resolving 'template:post', it would call
+  the `resolveTemplate` method.
+
+  Its last resort is to call the `resolveOther` method.
+
+  The methods of this object are designed to be easy to override
+  in a subclass. For example, you could enhance how a template
+  is resolved like so:
+
+  ```javascript
+  App = Ember.Application.create({
+    Resolver: Ember.DefaultResolver.extend({
+      resolveTemplate: function(parsedName) {
+        var resolvedTemplate = this._super(parsedName);
+        if (resolvedTemplate) { return resolvedTemplate; }
+        return Ember.TEMPLATES['not_found'];
+      }
+    })
+  });
+  ```
+
+  Some examples of how names are resolved:
+
+  ```
+  'template:post' //=> Ember.TEMPLATES['post']
+  'template:posts/byline' //=> Ember.TEMPLATES['posts/byline']
+  'template:posts.byline' //=> Ember.TEMPLATES['posts/byline']
+  'template:blogPost' //=> Ember.TEMPLATES['blogPost']
+                      //   OR
+                      //   Ember.TEMPLATES['blog_post']
+  'controller:post' //=> App.PostController
+  'controller:posts.index' //=> App.PostsIndexController
+  'controller:blog/post' //=> Blog.PostController
+  'controller:basic' //=> Ember.Controller
+  'route:post' //=> App.PostRoute
+  'route:posts.index' //=> App.PostsIndexRoute
+  'route:blog/post' //=> Blog.PostRoute
+  'route:basic' //=> Ember.Route
+  'view:post' //=> App.PostView
+  'view:posts.index' //=> App.PostsIndexView
+  'view:blog/post' //=> Blog.PostView
+  'view:basic' //=> Ember.View
+  'foo:post' //=> App.PostFoo
+  'model:post' //=> App.Post

+/**
+  An instance of `Ember.Application` is the starting point for every Ember
+  application. It helps to instantiate, initialize and coordinate the many
+  objects that make up your app.
+
+  Each Ember app has one and only one `Ember.Application` object. In fact, the
+  very first thing you should do in your application is create the instance:
+
+  ```javascript
+  window.App = Ember.Application.create();
+  ```
+
+  Typically, the application object is the only global variable. All other
+  classes in your app should be properties on the `Ember.Application` instance,
+  which highlights its first role: a global namespace.
+
+  For example, if you define a view class, it might look like this:
+
+  ```javascript
+  App.MyView = Ember.View.extend();
+  ```
+
+  By default, calling `Ember.Application.create()` will automatically initialize
+  your application by calling the `Ember.Application.initialize()` method. If
+  you need to delay initialization, you can call your app's `deferReadiness()`
+  method. When you are ready for your app to be initialized, call its
+  `advanceReadiness()` method.
+
+  You can define a `ready` method on the `Ember.Application` instance, which
+  will be run by Ember when the application is initialized.
+
+  Because `Ember.Application` inherits from `Ember.Namespace`, any classes
+  you create will have useful string representations when calling `toString()`.
+  See the `Ember.Namespace` documentation for more information.
+
+  While you can think of your `Ember.Application` as a container that holds the
+  other classes in your application, there are several other responsibilities
+  going on under-the-hood that you may want to understand.
+
+  ### Event Delegation
+
+  Ember uses a technique called _event delegation_. This allows the framework
+  to set up a global, shared event listener instead of requiring each view to
+  do it manually. For example, instead of each view registering its own
+  `mousedown` listener on its associated element, Ember sets up a `mousedown`
+  listener on the `body`.
+
+  If a `mousedown` event occurs, Ember will look at the target of the event and
+  start walking up the DOM node tree, finding corresponding views and invoking
+  their `mouseDown` method as it goes.
+
+  `Ember.Application` has a number of default events that it listens for, as
+  well as a mapping from lowercase events to camel-cased view method names. For
+  example, the `keypress` event causes the `keyPress` method on the view to be
+  called, the `dblclick` event causes `doubleClick` to be called, and so on.
+
+  If there is a bubbling browser event that Ember does not listen for by
+  default, you can specify custom events and their corresponding view method
+  names by setting the application's `customEvents` property:
+
+  ```javascript
+  App = Ember.Application.create({
+    customEvents: {
+      // add support for the paste event
+      paste: "paste"
+    }
+  });
+  ```
+
+  By default, the application sets up these event listeners on the document
+  body. However, in cases where you are embedding an Ember application inside
+  an existing page, you may want it to set up the listeners on an element
+  inside the body.
+
+  For example, if only events inside a DOM element with the ID of `ember-app`
+  should be delegated, set your application's `rootElement` property:
+
+  ```javascript
+  window.App = Ember.Application.create({
+    rootElement: '#ember-app'
+  });
+  ```
+
+  The `rootElement` can be either a DOM element or a jQuery-compatible selector
+  string. Note that *views appended to the DOM outside the root element will
+  not receive events.* If you specify a custom root element, make sure you only
+  append views inside it!
+
+  To learn more about the advantages of event delegation and the Ember view
+  layer, and a list of the event listeners that are setup by default, visit the
+  [Ember View Layer guide](http://emberjs.com/guides/understanding-ember/the-view-layer/#toc_event-dele...).
+
+  ### Initializers
+
+  Libraries on top of Ember can add initializers, like so:
+
+  ```javascript
+  Ember.Application.initializer({
+    name: 'api-adapter',
+
+    initialize: function(container, application) {
+      application.register('api-adapter:main', ApiAdapter);
+    }
+  });
+  ```
+
+  Initializers provide an opportunity to access the container, which
+  organizes the different components of an Ember application. Additionally
+  they provide a chance to access the instantiated application. Beyond
+  being used for libraries, initializers are also a great way to organize
+  dependency injection or setup in your own application.
+
+  ### Routing
+
+  In addition to creating your application's router, `Ember.Application` is
+  also responsible for telling the router when to start routing. Transitions
+  between routes can be logged with the `LOG_TRANSITIONS` flag, and more
+  detailed intra-transition logging can be logged with
+  the `LOG_TRANSITIONS_INTERNAL` flag:
+
+  ```javascript
+  window.App = Ember.Application.create({
+    LOG_TRANSITIONS: true, // basic logging of successful transitions
+    LOG_TRANSITIONS_INTERNAL: true // detailed logging of all routing steps
+  });
+  ```
+
+  By default, the router will begin trying to translate the current URL into
+  application state once the browser emits the `DOMContentReady` event. If you
+  need to defer routing, you can call the application's `deferReadiness()`
+  method. Once routing can begin, call the `advanceReadiness()` method.
+
+  If there is any setup required before routing begins, you can implement a
+  `ready()` method on your app that will be invoked immediately before routing
+  begins.
+  ```

+    Registers a factory that can be used for dependency injection (with
+    `App.inject`) or for service lookup. Each factory is registered with
+    a full name including two parts: `type:name`.
+
+    A simple example:
+
+    ```javascript
+    var App = Ember.Application.create();
+    App.Orange  = Ember.Object.extend();
+    App.register('fruit:favorite', App.Orange);
+    ```
+
+    Ember will resolve factories from the `App` namespace automatically.
+    For example `App.CarsController` will be discovered and returned if
+    an application requests `controller:cars`.
+
+    An example of registering a controller with a non-standard name:
+
+    ```javascript
+    var App = Ember.Application.create(),
+        Session  = Ember.Controller.extend();
+
+    App.register('controller:session', Session);
+
+    // The Session controller can now be treated like a normal controller,
+    // despite its non-standard name.
+    App.ApplicationController = Ember.Controller.extend({
+      needs: ['session']
+    });
+    ```
+
+    Registered factories are **instantiated** by having `create`
+    called on them. Additionally they are **singletons**, each time
+    they are looked up they return the same instance.
+
+    Some examples modifying that default behavior:
+
+    ```javascript
+    var App = Ember.Application.create();
+
+    App.Person  = Ember.Object.extend();
+    App.Orange  = Ember.Object.extend();
+    App.Email   = Ember.Object.extend();
+    App.session = Ember.Object.create();
+
+    App.register('model:user', App.Person, {singleton: false });
+    App.register('fruit:favorite', App.Orange);
+    App.register('communication:main', App.Email, {singleton: false});
+    App.register('session', App.session, {instantiate: false});
+    ```
+
+    @method register
+    @param  fullName {String} type:name (e.g., 'model:user')
+    @param  factory {Function} (e.g., App.Person)
+    @param  options {Object} (optional) disable instantiation or singleton usage
+  **/

+    var container = this.__container__;
+    container.register.apply(container, arguments);
+  },
+
+  /**
+    Define a dependency injection onto a specific factory or all factories
+    of a type.
+
+    When Ember instantiates a controller, view, or other framework component
+    it can attach a dependency to that component. This is often used to
+    provide services to a set of framework components.
+
+    An example of providing a session object to all controllers:
+
+    ```javascript
+    var App = Ember.Application.create(),
+        Session = Ember.Object.extend({ isAuthenticated: false });
+
+    // A factory must be registered before it can be injected
+    App.register('session:main', Session);
+
+    // Inject 'session:main' onto all factories of the type 'controller'
+    // with the name 'session'
+    App.inject('controller', 'session', 'session:main');
+
+    App.IndexController = Ember.Controller.extend({
+      isLoggedIn: Ember.computed.alias('session.isAuthenticated')
+    });
+    ```
+
+    Injections can also be performed on specific factories.
+
+    ```javascript
+    App.inject(<full_name or type>, <property name>, <full_name>)
+    App.inject('route', 'source', 'source:main')
+    App.inject('route:application', 'email', 'model:email')
+    ```
+
+    It is important to note that injections can only be performed on
+    classes that are instantiated by Ember itself. Instantiating a class
+    directly (via `create` or `new`) bypasses the dependency injection
+    system.
+
+    Ember-Data instantiates its models in a unique manner, and consequently
+    injections onto models (or all models) will not work as expected. Injections
+    on models can be enabled by setting `Ember.MODEL_FACTORY_INJECTIONS`
+    to `true`.

+    2. Destroy all objects in the container
+    3. Create a new application container
+    4. Re-route to the existing url
+
+    Typical Example:
+
+    ```javascript
+
+    var App;
+
+    Ember.run(function() {
+      App = Ember.Application.create();
+    });

+      // App is freshly reset
+    });
+
+    test("first test", function() {
+      // App is again freshly reset
+    });
+    ```
+
+    Advanced Example:
+
+    Occasionally you may want to prevent the app from initializing during
+    setup. This could enable extra configuration, or enable asserting prior
+    to the app becoming ready.
+
+    ```javascript
+
+    var App;
+
+    Ember.run(function() {
+      App = Ember.Application.create();
