+/**
+ * @ngdoc function
+ * @name angular.element
+ * @function
+ *
+ * @description
+ * Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element.
+ * `angular.element` can be either an alias for [jQuery](http://api.jquery.com/jQuery/) function, if
+ * jQuery is available, or a function that wraps the element or string in Angular's jQuery lite
+ * implementation (commonly referred to as jqLite).
+ *
+ * Real jQuery always takes precedence over jqLite, provided it was loaded before `DOMContentLoaded`
+ * event fired.
+ *
+ * jqLite is a tiny, API-compatible subset of jQuery that allows
+ * Angular to manipulate the DOM. jqLite implements only the most commonly needed functionality
+ * within a very small footprint, so only a subset of the jQuery API - methods, arguments and
+ * invocation styles - are supported.
+ *
+ * Note: All element references in Angular are always wrapped with jQuery or jqLite; they are never
+ * raw DOM references.
+ *
+ * ## Angular's jqLite
+ * Angular's lite version of jQuery provides only the following jQuery methods:
+ *
+ * - [addClass()](http://api.jquery.com/addClass/)
+ * - [after()](http://api.jquery.com/after/)
+ * - [append()](http://api.jquery.com/append/)
+ * - [attr()](http://api.jquery.com/attr/)
+ * - [bind()](http://api.jquery.com/bind/) - Does not support namespaces
+ * - [children()](http://api.jquery.com/children/) - Does not support selectors
+ * - [clone()](http://api.jquery.com/clone/)
+ * - [contents()](http://api.jquery.com/contents/)
+ * - [css()](http://api.jquery.com/css/)
+ * - [data()](http://api.jquery.com/data/)
+ * - [eq()](http://api.jquery.com/eq/)
+ * - [find()](http://api.jquery.com/find/) - Limited to lookups by tag name
+ * - [hasClass()](http://api.jquery.com/hasClass/)
+ * - [html()](http://api.jquery.com/html/)
+ * - [next()](http://api.jquery.com/next/) - Does not support selectors
+ * - [parent()](http://api.jquery.com/parent/) - Does not support selectors
+ * - [prepend()](http://api.jquery.com/prepend/)
+ * - [prop()](http://api.jquery.com/prop/)
+ * - [ready()](http://api.jquery.com/ready/)
+ * - [remove()](http://api.jquery.com/remove/)
+ * - [removeAttr()](http://api.jquery.com/removeAttr/)
+ * - [removeClass()](http://api.jquery.com/removeClass/)
+ * - [removeData()](http://api.jquery.com/removeData/)
+ * - [replaceWith()](http://api.jquery.com/replaceWith/)
+ * - [text()](http://api.jquery.com/text/)
+ * - [toggleClass()](http://api.jquery.com/toggleClass/)
+ * - [triggerHandler()](http://api.jquery.com/triggerHandler/) - Doesn't pass native event objects to handlers.
+ * - [unbind()](http://api.jquery.com/unbind/) - Does not support namespaces
+ * - [val()](http://api.jquery.com/val/)
+ * - [wrap()](http://api.jquery.com/wrap/)
+ *
+ * ## jQuery/jqLite Extras
+ * Angular also provides the following additional methods and events to both jQuery and jqLite:
+ *
+ * ### Events
+ * - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event
+ *    on all DOM nodes being removed.  This can be used to clean up and 3rd party bindings to the DOM
+ *    element before it is removed.
+ * ### Methods
+ * - `controller(name)` - retrieves the controller of the current element or its parent. By default
+ *   retrieves controller associated with the `ngController` directive. If `name` is provided as
+ *   camelCase directive name, then the controller for this directive will be retrieved (e.g.
+ *   `'ngModel'`).
+ * - `injector()` - retrieves the injector of the current element or its parent.
+ * - `scope()` - retrieves the {@link api/ng.$rootScope.Scope scope} of the current
+ *   element or its parent.
+ * - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top
+ *   parent element is reached.
+ *
+ * @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.
+ * @returns {Object} jQuery object.

+ * @ngdoc method

+ * @methodOf AUTO.$injector
+ *
+ * @description
+ * Returns an array of service names which the function is requesting for injection. This API is used by the injector
+ * to determine which services need to be injected into the function when the function is invoked. There are three
+ * ways in which the function can be annotated with the needed dependencies.
+ *
+ * # Argument names
+ *
+ * The simplest form is to extract the dependencies from the arguments of the function. This is done by converting
+ * the function into a string using `toString()` method and extracting the argument names.
+ * <pre>
+ *   // Given
+ *   function MyController($scope, $route) {
+ *     // ...
+ *   }
+ *
+ *   // Then
+ *   expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
+ * </pre>
+ *
+ * This method does not work with code minfication / obfuscation. For this reason the following annotation strategies
+ * are supported.
+ *
+ * # The `$inject` property
+ *
+ * If a function has an `$inject` property and its value is an array of strings, then the strings represent names of
+ * services to be injected into the function.
+ * <pre>
+ *   // Given
+ *   var MyController = function(obfuscatedScope, obfuscatedRoute) {
+ *     // ...
+ *   }
+ *   // Define function dependencies
+ *   MyController.$inject = ['$scope', '$route'];
+ *
+ *   // Then
+ *   expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
+ * </pre>
+ *
+ * # The array notation
+ *
+ * It is often desirable to inline Injected functions and that's when setting the `$inject` property is very
+ * inconvenient. In these situations using the array notation to specify the dependencies in a way that survives
+ * minification is a better choice:
+ *
+ * <pre>
+ *   // We wish to write this (not minification / obfuscation safe)
+ *   injector.invoke(function($compile, $rootScope) {
+ *     // ...
+ *   });
+ *
+ *   // We are forced to write break inlining
+ *   var tmpFn = function(obfuscatedCompile, obfuscatedRootScope) {
+ *     // ...
+ *   };
+ *   tmpFn.$inject = ['$compile', '$rootScope'];
+ *   injector.invoke(tmpFn);
+ *
+ *   // To better support inline function the inline annotation is supported
+ *   injector.invoke(['$compile', '$rootScope', function(obfCompile, obfRootScope) {
+ *     // ...
+ *   }]);
+ *
+ *   // Therefore
+ *   expect(injector.annotate(
+ *      ['$compile', '$rootScope', function(obfus_$compile, obfus_$rootScope) {}])
+ *    ).toEqual(['$compile', '$rootScope']);
+ * </pre>
+ *
+ * @param {function|Array.<string|Function>} fn Function for which dependent service names need to be retrieved as described
+ *   above.
+ *
+ * @returns {Array.<string>} The names of the services which the function requires.

+ *
+ * @param {string|DOMElement} element Element or HTML string to compile into a template function.
+ * @param {function(angular.Scope[, cloneAttachFn]} transclude function available to directives.
+ * @param {number} maxPriority only apply directives lower then given priority (Only effects the
+ *                 root element(s), not their children)
+ * @returns {function(scope[, cloneAttachFn])} a link function which is used to bind template
+ * (a DOM element/tree) to a scope. Where:
+ *
+ *  * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to.
+ *  * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the
+ *               `template` and call the `cloneAttachFn` function allowing the caller to attach the
+ *               cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is
+ *               called as: <br> `cloneAttachFn(clonedElement, scope)` where:
+ *
+ *      * `clonedElement` - is a clone of the original `element` passed into the compiler.
+ *      * `scope` - is the current scope with which the linking function is working with.
+ *
+ * Calling the linking function returns the element of the template. It is either the original element
+ * passed in, or the clone of the element if the `cloneAttachFn` is provided.
+ *
+ * After linking the view is not updated until after a call to $digest which typically is done by
+ * Angular automatically.
+ *
+ * If you need access to the bound view, there are two ways to do it:
+ *
+ * - If you are not asking the linking function to clone the template, create the DOM element(s)
+ *   before you send them to the compiler and keep this reference around.
+ *   <pre>
+ *     var element = $compile('<p>{{total}}</p>')(scope);
+ *   </pre>
+ *
+ * - if on the other hand, you need the element to be cloned, the view reference from the original
+ *   example would not point to the clone, but rather to the original template that was cloned. In
+ *   this case, you can access the clone via the cloneAttachFn:
+ *   <pre>
+ *     var templateHTML = angular.element('<p>{{total}}</p>'),
+ *         scope = ....;
+ *
+ *     var clonedElement = $compile(templateHTML)(scope, function(clonedElement, scope) {
+ *       //attach the clone to DOM document at the right place
+ *     });
+ *
+ *     //now we have reference to the cloned DOM via `clone`
+ *   </pre>
+ *
+ *
+ * For information on how the compiler works, see the
+ * {@link guide/compiler Angular HTML Compiler} section of the Developer Guide.

+ * @ngdoc service
+ * @name ng.$q
+ * @requires $rootScope
+ *
+ * @description
+ * A promise/deferred implementation inspired by [Kris Kowal's Q](https://github.com/kriskowal/q).
+ *
+ * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an
+ * interface for interacting with an object that represents the result of an action that is
+ * performed asynchronously, and may or may not be finished at any given point in time.
+ *
+ * From the perspective of dealing with error handling, deferred and promise APIs are to
+ * asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming.
+ *
+ * <pre>
+ *   // for the purpose of this example let's assume that variables `$q` and `scope` are
+ *   // available in the current lexical scope (they could have been injected or passed in).
+ *
+ *   function asyncGreet(name) {
+ *     var deferred = $q.defer();
+ *
+ *     setTimeout(function() {
+ *       // since this fn executes async in a future turn of the event loop, we need to wrap
+ *       // our code into an $apply call so that the model changes are properly observed.
+ *       scope.$apply(function() {
+ *         if (okToGreet(name)) {
+ *           deferred.resolve('Hello, ' + name + '!');
+ *         } else {
+ *           deferred.reject('Greeting ' + name + ' is not allowed.');
+ *         }
+ *       });
+ *     }, 1000);
+ *
+ *     return deferred.promise;
+ *   }
+ *
+ *   var promise = asyncGreet('Robin Hood');
+ *   promise.then(function(greeting) {
+ *     alert('Success: ' + greeting);
+ *   }, function(reason) {
+ *     alert('Failed: ' + reason);
+ *   });
+ * </pre>
+ *
+ * At first it might not be obvious why this extra complexity is worth the trouble. The payoff
+ * comes in the way of
+ * [guarantees that promise and deferred APIs make](https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.m...).
+ *
+ * Additionally the promise api allows for composition that is very hard to do with the
+ * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach.
+ * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the
+ * section on serial or parallel joining of promises.
+ *
+ *
+ * # The Deferred API
+ *
+ * A new instance of deferred is constructed by calling `$q.defer()`.
+ *
+ * The purpose of the deferred object is to expose the associated Promise instance as well as APIs
+ * that can be used for signaling the successful or unsuccessful completion of the task.
+ *
+ * **Methods**
+ *
+ * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection
+ *   constructed via `$q.reject`, the promise will be rejected instead.
+ * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to
+ *   resolving it with a rejection constructed via `$q.reject`.
+ *
+ * **Properties**
+ *
+ * - promise – `{Promise}` – promise object associated with this deferred.
+ *
+ *
+ * # The Promise API
+ *
+ * A new promise instance is created when a deferred instance is created and can be retrieved by
+ * calling `deferred.promise`.
+ *
+ * The purpose of the promise object is to allow for interested parties to get access to the result
+ * of the deferred task when it completes.
+ *
+ * **Methods**
+ *
+ * - `then(successCallback, errorCallback)` – regardless of when the promise was or will be resolved
+ *   or rejected, `then` calls one of the success or error callbacks asynchronously as soon as the result
+ *   is available. The callbacks are called with a single argument: the result or rejection reason.
+ *
+ *   This method *returns a new promise* which is resolved or rejected via the return value of the
+ *   `successCallback` or `errorCallback`.
+ *
+ *
+ * # Chaining promises
+ *
+ * Because calling the `then` method of a promise returns a new derived promise, it is easily possible
+ * to create a chain of promises:
+ *
+ * <pre>
+ *   promiseB = promiseA.then(function(result) {
+ *     return result + 1;
+ *   });
+ *
+ *   // promiseB will be resolved immediately after promiseA is resolved and its value
+ *   // will be the result of promiseA incremented by 1
+ * </pre>
+ *
+ * It is possible to create chains of any length and since a promise can be resolved with another
+ * promise (which will defer its resolution further), it is possible to pause/defer resolution of
+ * the promises at any point in the chain. This makes it possible to implement powerful APIs like
+ * $http's response interceptors.
+ *
+ *
+ * # Differences between Kris Kowal's Q and $q
+ *
+ *  There are three main differences:
+ *
+ * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation
+ *   mechanism in angular, which means faster propagation of resolution or rejection into your
+ *   models and avoiding unnecessary browser repaints, which would result in flickering UI.
+ * - $q promises are recognized by the templating engine in angular, which means that in templates
+ *   you can treat promises attached to a scope as if they were the resulting values.
+ * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains
+ *   all the important functionality needed for common async tasks.
+ * 
+ *  # Testing
+ * 
+ *  <pre>
+ *    it('should simulate promise', inject(function($q, $rootScope) {
+ *      var deferred = $q.defer();
+ *      var promise = deferred.promise;
+ *      var resolvedValue;
+ * 
+ *      promise.then(function(value) { resolvedValue = value; });
+ *      expect(resolvedValue).toBeUndefined();
+ * 
+ *      // Simulate resolving of promise
+ *      deferred.resolve(123);
+ *      // Note that the 'then' function does not get called synchronously.
+ *      // This is because we want the promise API to always be async, whether or not
+ *      // it got called synchronously or asynchronously.
+ *      expect(resolvedValue).toBeUndefined();
+ * 
+ *      // Propagate promise resolution to 'then' functions using $apply().
+ *      $rootScope.$apply();
+ *      expect(resolvedValue).toEqual(123);
+ *    });

+   *    contains redundant trailing slash or is missing one, the route will still match and the
+   *    `$location.path` will be updated to add or drop the trailing slash to exactly match the
+   *    route definition.
+   *
+   *    `path` can contain named groups starting with a colon (`:name`). All characters up to the
+   *    next slash are matched and stored in `$routeParams` under the given `name` after the route
+   *    is resolved.

+   *      created scope or the name of a {@link angular.Module#controller registered controller}
+   *      if passed as a string.
+   *    - `template` – `{string=}` –  html template as a string that should be used by
+   *      {@link ng.directive:ngView ngView} or
+   *      {@link ng.directive:ngInclude ngInclude} directives.
+   *      this property takes precedence over `templateUrl`.
+   *    - `templateUrl` – `{string=}` – path to an html template that should be used by
+   *      {@link ng.directive:ngView ngView}.
+   *    - `resolve` - `{Object.<string, function>=}` - An optional map of dependencies which should
+   *      be injected into the controller. If any of these dependencies are promises, they will be
+   *      resolved and converted to a value before the controller is instantiated and the
+   *      `$routeChangeSuccess` event is fired. The map object is:
+   *
+   *      - `key` – `{string}`: a name of a dependency to be injected into the controller.
+   *      - `factory` - `{string|function}`: If `string` then it is an alias for a service.
+   *        Otherwise if function, then it is {@link api/AUTO.$injector#invoke injected}
+   *        and the return value is treated as the dependency. If the result is a promise, it is resolved
+   *        before its value is injected into the controller. Be aware that `ngRoute.$routeParams` will
+   *        still refer to the previous route within these resolve functions.  Use `$route.current.params`
+   *        to access the new route parameters, instead.
+   *
+   *    - `redirectTo` – {(string|function())=} – value to update
+   *      {@link ng.$location $location} path with and trigger route redirection.
+   *
+   *      If `redirectTo` is a function, it will be called with the following parameters:
+   *
+   *      - `{Object.<string>}` - route parameters extracted from the current
+   *        `$location.path()` by applying the current route templateUrl.
+   *      - `{string}` - current `$location.path()`
+   *      - `{Object}` - current `$location.search()`
+   *
+   *      The custom `redirectTo` function is expected to return a string which will be used
+   *      to update `$location.path()` and `$location.search()`.
+   *
+   *    - `[reloadOnSearch=true]` - {boolean=} - reload route when only $location.search()
+   *    changes.
+   *
+   *      If the option is set to `false` and url in the browser changes, then
+   *      `$routeUpdate` event is broadcasted on the root scope.

+ * @description
+ * Current set of route parameters. The route parameters are a combination of the
+ * {@link ng.$location $location} `search()`, and `path()`. The `path` parameters
+ * are extracted when the {@link ng.$route $route} path is matched.
+ *
+ * In case of parameter name collision, `path` params take precedence over `search` params.
+ *
+ * The service guarantees that the identity of the `$routeParams` object will remain unchanged
+ * (but its properties will likely change) even when a route change occurs.
+ *
+ * Note that the `$routeParams` are only updated *after* a route change completes successfully.
+ * This means that you cannot rely on `$routeParams` being correct in route resolve functions.
+ * Instead you can use `$route.current.params` to access the new route's parameters.
+ *
+ * @example
+ * <pre>
+ *  // Given:
+ *  // URL: http://server.com/index.html#/Chapter/1/Section/2?search=moby
+ *  // Route: /Chapter/:chapterId/Section/:sectionId

+/**
+ * DESIGN NOTES
+ *
+ * The design decisions behind the scope are heavily favored for speed and memory consumption.
+ *
+ * The typical use of scope is to watch the expressions, which most of the time return the same
+ * value as last time so we optimize the operation.
+ *
+ * Closures construction is expensive in terms of speed as well as memory:
+ *   - No closures, instead use prototypical inheritance for API
+ *   - Internal state needs to be stored on scope directly, which means that private state is
+ *     exposed as $$____ properties
+ *
+ * Loop operations are optimized by using while(count--) { ... }
+ *   - this means that in order to keep the same order of execution as addition we have to add
+ *     items to the array at the beginning (shift) instead of at the end (push)
+ *
+ * Child scopes are created and removed often
+ *   - Using an array would be slow since inserts in middle are expensive so we use linked list
+ *
+ * There are few watches then a lot of observers. This is why you don't want the observer to be
+ * implemented in the same way as watch. Watch requires return of initialization function which
+ * are expensive to construct.

+       *   {@link ng.$rootScope.Scope#$digest $digest()} and should be idempotent.)
+       * - The `listener` is called only when the value from the current `watchExpression` and the
+       *   previous call to `watchExpression` are not equal (with the exception of the initial run,
+       *   see below). The inequality is determined according to
+       *   {@link angular.equals} function. To save the value of the object for later comparison, the
+       *   {@link angular.copy} function is used. It also means that watching complex options will
+       *   have adverse memory and performance implications.
+       * - The watch `listener` may change the model, which may trigger other `listener`s to fire. This
+       *   is achieved by rerunning the watchers until no changes are detected. The rerun iteration
+       *   limit is 10 to prevent an infinite loop deadlock.
+       *
+       *
+       * If you want to be notified whenever {@link ng.$rootScope.Scope#$digest $digest} is called,
+       * you can register a `watchExpression` function with no `listener`. (Since `watchExpression`
+       * can execute multiple times per {@link ng.$rootScope.Scope#$digest $digest} cycle when a change is
+       * detected, be prepared for multiple calls to your listener.)
+       *
+       * After a watcher is registered with the scope, the `listener` fn is called asynchronously
+       * (via {@link ng.$rootScope.Scope#$evalAsync $evalAsync}) to initialize the
+       * watcher. In rare cases, this is undesirable because the listener is called when the result
+       * of `watchExpression` didn't change. To detect this scenario within the `listener` fn, you
+       * can compare the `newVal` and `oldVal`. If these two values are identical (`===`) then the
+       * listener was called due to initialization.

+     * @description
+     * The `$http` service is a core Angular service that facilitates communication with the remote
+     * HTTP servers via the browser's {@link https://developer.mozilla.org/en/xmlhttprequest
+     * XMLHttpRequest} object or via {@link http://en.wikipedia.org/wiki/JSONP JSONP}.
+     *
+     * For unit testing applications that use `$http` service, see
+     * {@link ngMock.$httpBackend $httpBackend mock}.
+     *
+     * For a higher level of abstraction, please check out the {@link ngResource.$resource
+     * $resource} service.
+     *
+     * The $http API is based on the {@link ng.$q deferred/promise APIs} exposed by
+     * the $q service. While for simple usage patterns this doesn't matter much, for advanced usage
+     * it is important to familiarize yourself with these APIs and the guarantees they provide.
+     *
+     *
+     * # General usage
+     * The `$http` service is a function which takes a single argument — a configuration object —
+     * that is used to generate an HTTP request and returns  a {@link ng.$q promise}
+     * with two $http specific methods: `success` and `error`.
+     *
+     * <pre>
+     *   $http({method: 'GET', url: '/someUrl'}).
+     *     success(function(data, status, headers, config) {
+     *       // this callback will be called asynchronously
+     *       // when the response is available
+     *     }).
+     *     error(function(data, status, headers, config) {
+     *       // called asynchronously if an error occurs
+     *       // or server returns response with an error status.
+     *     });
+     * </pre>
+     *
+     * Since the returned value of calling the $http function is a `promise`, you can also use
+     * the `then` method to register callbacks, and these callbacks will receive a single argument –
+     * an object representing the response. See the API signature and type info below for more
+     * details.
+     *
+     * A response status code between 200 and 299 is considered a success status and
+     * will result in the success callback being called. Note that if the response is a redirect,
+     * XMLHttpRequest will transparently follow it, meaning that the error callback will not be
+     * called for such responses.
+     *
+     * # Shortcut methods
+     *
+     * Since all invocations of the $http service require passing in an HTTP method and URL, and
+     * POST/PUT requests require request data to be provided as well, shortcut methods
+     * were created:
+     *
+     * <pre>
+     *   $http.get('/someUrl').success(successCallback);
+     *   $http.post('/someUrl', data).success(successCallback);
+     * </pre>
+     *
+     * Complete list of shortcut methods:
+     *
+     * - {@link ng.$http#get $http.get}
+     * - {@link ng.$http#head $http.head}
+     * - {@link ng.$http#post $http.post}
+     * - {@link ng.$http#put $http.put}
+     * - {@link ng.$http#delete $http.delete}
+     * - {@link ng.$http#jsonp $http.jsonp}
+     *
+     *
+     * # Setting HTTP Headers
+     *
+     * The $http service will automatically add certain HTTP headers to all requests. These defaults
+     * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration
+     * object, which currently contains this default configuration:
+     *
+     * - `$httpProvider.defaults.headers.common` (headers that are common for all requests):
+     *   - `Accept: application/json, text/plain, * / *`
+     *   - `X-Requested-With: XMLHttpRequest`
+     * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests)
+     *   - `Content-Type: application/json`
+     * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests)
+     *   - `Content-Type: application/json`
+     *
+     * To add or overwrite these defaults, simply add or remove a property from these configuration
+     * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object
+     * with the lowercased HTTP method name as the key, e.g.
+     * `$httpProvider.defaults.headers.get['My-Header']='value'`.
+     *
+     * Additionally, the defaults can be set at runtime via the `$http.defaults` object in the same
+     * fashion.
+     *
+     *
+     * # Transforming Requests and Responses
+     *
+     * Both requests and responses can be transformed using transform functions. By default, Angular
+     * applies these transformations:
+     *
+     * Request transformations:
+     *
+     * - If the `data` property of the request configuration object contains an object, serialize it into
+     *   JSON format.
+     *
+     * Response transformations:
+     *
+     *  - If XSRF prefix is detected, strip it (see Security Considerations section below).
+     *  - If JSON response is detected, deserialize it using a JSON parser.
+     *
+     * To globally augment or override the default transforms, modify the `$httpProvider.defaults.transformRequest` and
+     * `$httpProvider.defaults.transformResponse` properties. These properties are by default an
+     * array of transform functions, which allows you to `push` or `unshift` a new transformation function into the
+     * transformation chain. You can also decide to completely override any default transformations by assigning your
+     * transformation functions to these properties directly without the array wrapper.
+     *
+     * Similarly, to locally override the request/response transforms, augment the `transformRequest` and/or
+     * `transformResponse` properties of the configuration object passed into `$http`.
+     *
+     *
+     * # Caching
+     *
+     * To enable caching, set the configuration property `cache` to `true`. When the cache is
+     * enabled, `$http` stores the response from the server in local cache. Next time the
+     * response is served from the cache without sending a request to the server.
+     *
+     * Note that even if the response is served from cache, delivery of the data is asynchronous in
+     * the same way that real requests are.
+     *
+     * If there are multiple GET requests for the same URL that should be cached using the same
+     * cache, but the cache is not populated yet, only one request to the server will be made and
+     * the remaining requests will be fulfilled using the response from the first request.
+     *
+     *
+     * # Response interceptors
+     *
+     * Before you start creating interceptors, be sure to understand the
+     * {@link ng.$q $q and deferred/promise APIs}.
+     *
+     * For purposes of global error handling, authentication or any kind of synchronous or
+     * asynchronous preprocessing of received responses, it is desirable to be able to intercept
+     * responses for http requests before they are handed over to the application code that
+     * initiated these requests. The response interceptors leverage the {@link ng.$q
+     * promise apis} to fulfil this need for both synchronous and asynchronous preprocessing.
+     *
+     * The interceptors are service factories that are registered with the $httpProvider by
+     * adding them to the `$httpProvider.responseInterceptors` array. The factory is called and
+     * injected with dependencies (if specified) and returns the interceptor  — a function that
+     * takes a {@link ng.$q promise} and returns the original or a new promise.
+     *
+     * <pre>
+     *   // register the interceptor as a service
+     *   $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
+     *     return function(promise) {
+     *       return promise.then(function(response) {
+     *         // do something on success
+     *         return response;
+     *       }, function(response) {
+     *         // do something on error
+     *         if (canRecover(response)) {
+     *           return responseOrNewPromise
+     *         }
+     *         return $q.reject(response);
+     *       });
+     *     }
+     *   });
+     *
+     *   $httpProvider.responseInterceptors.push('myHttpInterceptor');
+     *
+     *
+     *   // register the interceptor via an anonymous factory
+     *   $httpProvider.responseInterceptors.push(function($q, dependency1, dependency2) {
+     *     return function(promise) {
+     *       // same as above
+     *     }
+     *   });
+     * </pre>
+     *
+     *
+     * # Security Considerations
+     *
+     * When designing web applications, consider security threats from:
+     *
+     * - {@link http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability...
+     *   JSON vulnerability}
+     * - {@link http://en.wikipedia.org/wiki/Cross-site_request_forgery XSRF}
+     *
+     * Both server and the client must cooperate in order to eliminate these threats. Angular comes
+     * pre-configured with strategies that address these issues, but for this to work backend server
+     * cooperation is required.
+     *
+     * ## JSON Vulnerability Protection
+     *
+     * A {@link http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability...
+     * JSON vulnerability} allows third party website to turn your JSON resource URL into
+     * {@link http://en.wikipedia.org/wiki/JSONP JSONP} request under some conditions. To
+     * counter this your server can prefix all JSON requests with following string `")]}',\n"`.
+     * Angular will automatically strip the prefix before processing it as JSON.
+     *
+     * For example if your server needs to return:
+     * <pre>
+     * ['one','two']
+     * </pre>
+     *
+     * which is vulnerable to attack, your server can return:
+     * <pre>
+     * )]}',
+     * ['one','two']
+     * </pre>
+     *
+     * Angular will strip the prefix, before processing the JSON.
+     *
+     *
+     * ## Cross Site Request Forgery (XSRF) Protection
+     *
+     * {@link http://en.wikipedia.org/wiki/Cross-site_request_forgery XSRF} is a technique by which
+     * an unauthorized site can gain your user's private data. Angular provides a mechanism
+     * to counter XSRF. When performing XHR requests, the $http service reads a token from a cookie
+     * called `XSRF-TOKEN` and sets it as the HTTP header `X-XSRF-TOKEN`. Since only JavaScript that
+     * runs on your domain could read the cookie, your server can be assured that the XHR came from
+     * JavaScript running on your domain.
+     *
+     * To take advantage of this, your server needs to set a token in a JavaScript readable session
+     * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the
+     * server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure
+     * that only JavaScript running on your domain could have sent the request. The token must be
+     * unique for each user and must be verifiable by the server (to prevent the JavaScript from making
+     * up its own tokens). We recommend that the token is a digest of your site's authentication
+     * cookie with a {@link https://en.wikipedia.org/wiki/Salt_(cryptography) salt} for added security.
+     *
+     *
+     * @param {object} config Object describing the request to be made and how it should be
+     *    processed. The object has following properties:
+     *
+     *    - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)
+     *    - **url** – `{string}` – Absolute or relative URL of the resource that is being requested.
+     *    - **params** – `{Object.<string|Object>}` – Map of strings or objects which will be turned to
+     *      `?key1=value1&key2=value2` after the url. If the value is not a string, it will be JSONified.
+     *    - **data** – `{string|Object}` – Data to be sent as the request message data.
+     *    - **headers** – `{Object}` – Map of strings representing HTTP headers to send to the server.
+     *    - **transformRequest** – `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
+     *      transform function or an array of such functions. The transform function takes the http
+     *      request body and headers and returns its transformed (typically serialized) version.
+     *    - **transformResponse** – `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
+     *      transform function or an array of such functions. The transform function takes the http
+     *      response body and headers and returns its transformed (typically deserialized) version.
+     *    - **cache** – `{boolean|Cache}` – If true, a default $http cache will be used to cache the
+     *      GET request, otherwise if a cache instance built with
+     *      {@link ng.$cacheFactory $cacheFactory}, this cache will be used for
+     *      caching.
+     *    - **timeout** – `{number}` – timeout in milliseconds.
+     *    - **withCredentials** - `{boolean}` - whether to to set the `withCredentials` flag on the
+     *      XHR object. See {@link https://developer.mozilla.org/en/http_access_control#section_5
+     *      requests with credentials} for more information.
+     *
+     * @returns {HttpPromise} Returns a {@link ng.$q promise} object with the
+     *   standard `then` method and two http specific methods: `success` and `error`. The `then`
+     *   method takes two arguments a success and an error callback which will be called with a
+     *   response object. The `success` and `error` methods take a single argument - a function that
+     *   will be called when the request succeeds or fails respectively. The arguments passed into
+     *   these functions are destructured representation of the response object passed into the
+     *   `then` method. The response object has these properties:
+     *
+     *   - **data** – `{string|Object}` – The response body transformed with the transform functions.
+     *   - **status** – `{number}` – HTTP status code of the response.
+     *   - **headers** – `{function([headerName])}` – Header getter function.
+     *   - **config** – `{Object}` – The configuration object that was used to generate the request.
+     *
+     * @property {Array.<Object>} pendingRequests Array of config objects for currently pending
+     *   requests. This is primarily meant to be used for debugging purposes.

+ * Filters are just functions which transform input to an output. However filters need to be Dependency Injected. To
+ * achieve this a filter definition consists of a factory function which is annotated with dependencies and is
+ * responsible for creating a filter function.
+ *
+ * <pre>
+ *   // Filter registration
+ *   function MyModule($provide, $filterProvider) {
+ *     // create a service to demonstrate injection (not always needed)
+ *     $provide.value('greet', function(name){
+ *       return 'Hello ' + name + '!';
+ *     });
+ *
+ *     // register a filter factory which uses the
+ *     // greet service to demonstrate DI.
+ *     $filterProvider.register('greet', function(greet){
+ *       // return the filter function which uses the greet service
+ *       // to generate salutation
+ *       return function(text) {
+ *         // filters need to be forgiving so check input validity
+ *         return text && greet(text) || text;
+ *       };
+ *     });
+ *   }
+ * </pre>
+ *
+ * The filter function is registered with the `$injector` under the filter name suffixe with `Filter`.
+ * <pre>
+ *   it('should be the same instance', inject(
+ *     function($filterProvider) {
+ *       $filterProvider.register('reverse', function(){
+ *         return ...;

+ *     },

+ * @ngdoc filter
+ * @name ng.filter:filter
+ * @function
+ *
+ * @description
+ * Selects a subset of items from `array` and returns it as a new array.
+ *
+ * Note: This function is used to augment the `Array` type in Angular expressions. See
+ * {@link ng.$filter} for more information about Angular arrays.
+ *
+ * @param {Array} array The source array.
+ * @param {string|Object|function()} expression The predicate to be used for selecting items from
+ *   `array`.
+ *
+ *   Can be one of:
+ *
+ *   - `string`: Predicate that results in a substring match using the value of `expression`
+ *     string. All strings or objects with string properties in `array` that contain this string
+ *     will be returned. The predicate can be negated by prefixing the string with `!`.
+ *
+ *   - `Object`: A pattern object can be used to filter specific properties on objects contained
+ *     by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items
+ *     which have property `name` containing "M" and property `phone` containing "1". A special
+ *     property name `$` can be used (as in `{$:"text"}`) to accept a match against any
+ *     property of the object. That's equivalent to the simple substring match with a `string`
+ *     as described above.
+ *
+ *   - `function`: A predicate function can be used to write arbitrary filters. The function is
+ *     called for each element of `array`. The final result is an array of those elements that
+ *     the predicate returned true for.

+ *   `format` string can be composed of the following elements:
+ *
+ *   * `'yyyy'`: 4 digit representation of year (e.g. AD 1 => 0001, AD 2010 => 2010)
+ *   * `'yy'`: 2 digit representation of year, padded (00-99). (e.g. AD 2001 => 01, AD 2010 => 10)
+ *   * `'y'`: 1 digit representation of year, e.g. (AD 1 => 1, AD 199 => 199)
+ *   * `'MMMM'`: Month in year (January-December)
+ *   * `'MMM'`: Month in year (Jan-Dec)
+ *   * `'MM'`: Month in year, padded (01-12)
+ *   * `'M'`: Month in year (1-12)
+ *   * `'dd'`: Day in month, padded (01-31)
+ *   * `'d'`: Day in month (1-31)
+ *   * `'EEEE'`: Day in Week,(Sunday-Saturday)
+ *   * `'EEE'`: Day in Week, (Sun-Sat)
+ *   * `'HH'`: Hour in day, padded (00-23)
+ *   * `'H'`: Hour in day (0-23)
+ *   * `'hh'`: Hour in am/pm, padded (01-12)
+ *   * `'h'`: Hour in am/pm, (1-12)
+ *   * `'mm'`: Minute in hour, padded (00-59)
+ *   * `'m'`: Minute in hour (0-59)
+ *   * `'ss'`: Second in minute, padded (00-59)
+ *   * `'s'`: Second in minute (0-59)
+ *   * `'a'`: am/pm marker
+ *   * `'Z'`: 4 digit (+sign) representation of the timezone offset (-1200-+1200)
+ *
+ *   `format` string can also be one of the following predefined
+ *   {@link guide/i18n localizable formats}:
+ *
+ *   * `'medium'`: equivalent to `'MMM d, y h:mm:ss a'` for en_US locale
+ *     (e.g. Sep 3, 2010 12:05:08 pm)
+ *   * `'short'`: equivalent to `'M/d/yy h:mm a'` for en_US  locale (e.g. 9/3/10 12:05 pm)
+ *   * `'fullDate'`: equivalent to `'EEEE, MMMM d,y'` for en_US  locale
+ *     (e.g. Friday, September 3, 2010)
+ *   * `'longDate'`: equivalent to `'MMMM d, y'` for en_US  locale (e.g. September 3, 2010)
+ *   * `'mediumDate'`: equivalent to `'MMM d, y'` for en_US  locale (e.g. Sep 3, 2010)
+ *   * `'shortDate'`: equivalent to `'M/d/yy'` for en_US locale (e.g. 9/3/10)
+ *   * `'mediumTime'`: equivalent to `'h:mm:ss a'` for en_US locale (e.g. 12:05:08 pm)
+ *   * `'shortTime'`: equivalent to `'h:mm a'` for en_US locale (e.g. 12:05 pm)
+ *
+ *   `format` string can contain literal values. These need to be quoted with single quotes (e.g.
+ *   `"h 'in the morning'"`). In order to output single quote, use two single quotes in a sequence
+ *   (e.g. `"h 'o''clock'"`).
+ *
+ * @param {(Date|number|string)} date Date to format either as Date object, milliseconds (string or
+ *    number) or various ISO 8601 datetime string formats (e.g. yyyy-MM-ddTHH:mm:ss.SSSZ and its
+ *    shorter versions like yyyy-MM-ddTHH:mmZ, yyyy-MM-dd or yyyyMMddTHHmmssZ). If no timezone is
+ *    specified in the string input, the time is considered to be in the local timezone.
+ * @param {string=} format Formatting rules (see Description). If not specified,
+ *    `mediumDate` is used.
+ * @returns {string} Formatted string or the input if input is not recognized as date/millis.

+ *
+ * # Alias: {@link ng.directive:ngForm `ngForm`}
+ *
+ * In angular forms can be nested. This means that the outer form is valid when all of the child
+ * forms are valid as well. However browsers do not allow nesting of `<form>` elements, for this
+ * reason angular provides {@link ng.directive:ngForm `ngForm`} alias
+ * which behaves identical to `<form>` but allows form nesting.
+ *
+ *
+ * # CSS classes
+ *  - `ng-valid` Is set if the form is valid.
+ *  - `ng-invalid` Is set if the form is invalid.
+ *  - `ng-pristine` Is set if the form is pristine.
+ *  - `ng-dirty` Is set if the form is dirty.
+ *
+ *
+ * # Submitting a form and preventing default action
+ *
+ * Since the role of forms in client-side Angular applications is different than in classical
+ * roundtrip apps, it is desirable for the browser not to translate the form submission into a full
+ * page reload that sends the data to the server. Instead some javascript logic should be triggered
+ * to handle the form submission in application specific way.
+ *
+ * For this reason, Angular prevents the default action (form submission to the server) unless the
+ * `<form>` element has an `action` attribute specified.
+ *
+ * You can use one of the following two ways to specify what javascript method should be called when
+ * a form is submitted:
+ *
+ * - {@link ng.directive:ngSubmit ngSubmit} directive on the form element
+ * - {@link ng.directive:ngClick ngClick} directive on the first
+  *  button or input field of type submit (input[type=submit])
+ *
+ * To prevent double execution of the handler, use only one of ngSubmit or ngClick directives. This
+ * is because of the following form submission rules coming from the html spec:
+ *
+ * - If a form has only one input field then hitting enter in this field triggers form submit
+ * (`ngSubmit`)
+ * - if a form has has 2+ input fields and no buttons or input[type=submit] then hitting enter
+ * doesn't trigger submit
+ * - if a form has one or more input fields and one or more buttons or input[type=submit] then
+ * hitting enter in any of the input fields will trigger the click handler on the *first* button or
+ * input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`)
+ *
+ * @param {string=} name Name of the form. If specified, the form controller will be published into
+ *                       related scope, under this name.

+ * `NgModelController` provides API for the `ng-model` directive. The controller contains
+ * services for data-binding, validation, CSS update, value formatting and parsing. It
+ * specifically does not contain any logic which deals with DOM rendering or listening to
+ * DOM events. The `NgModelController` is meant to be extended by other directives where, the
+ * directive provides DOM manipulation and the `NgModelController` provides the data-binding.
+ * Note that you cannot use `NgModelController` in a directive with an isolated scope,
+ * as, in that case, the `ng-model` value gets put into the isolated scope and does not get
+ * propogated to the parent scope.
+ *
+ *
+ * This example shows how to use `NgModelController` with a custom control to achieve
+ * data-binding. Notice how different directives (`contenteditable`, `ng-model`, and `required`)
+ * collaborate together to achieve the desired result.
+ *
+ * <example module="customControl">

+      [contenteditable] {

+ * @ngdoc directive
+ * @name ng.directive:ngModel
+ *
+ * @element input
+ *
+ * @description
+ * Is a directive that tells Angular to do two-way data binding. It works together with `input`,
+ * `select`, `textarea`. You can easily write your own directives to use `ngModel` as well.
+ *
+ * `ngModel` is responsible for:
+ *
+ * - binding the view into the model, which other directives such as `input`, `textarea` or `select`
+ *   require,
+ * - providing validation behavior (i.e. required, number, email, url),
+ * - keeping state of the control (valid/invalid, dirty/pristine, validation errors),
+ * - setting related css class onto the element (`ng-valid`, `ng-invalid`, `ng-dirty`, `ng-pristine`),
+ * - register the control with parent {@link ng.directive:form form}.
+ *
+ * Note: `ngModel` will try to bind to the property given by evaluating the expression on the
+ * current scope. If the property doesn't already exist on this scope, it will be created
+ * implicitly and added to the scope.
+ *
+ * For basic examples, how to use `ngModel`, see:
+ *
+ *  - {@link ng.directive:input input}
+ *    - {@link ng.directive:input.text text}
+ *    - {@link ng.directive:input.checkbox checkbox}
+ *    - {@link ng.directive:input.radio radio}
+ *    - {@link ng.directive:input.number number}
+ *    - {@link ng.directive:input.email email}

+ *
+ * Typically, you don't use `ngBind` directly, but instead you use the double curly markup like

+ *
+ * It is preferrable to use `ngBind` instead of `{{ expression }}` when a template is momentarily 
+ * displayed by the browser in its raw state before Angular compiles it. Since `ngBind` is an 
+ * element attribute, it makes the bindings invisible to the user while the page is loading.

+ * An alternative solution to this problem would be using the

+/**
+ * @ngdoc directive
+ * @name ng.directive:ngCloak
+ *
+ * @description
+ * The `ngCloak` directive is used to prevent the Angular html template from being briefly
+ * displayed by the browser in its raw (uncompiled) form while your application is loading. Use this
+ * directive to avoid the undesirable flicker effect caused by the html template display.
+ *
+ * The directive can be applied to the `<body>` element, but typically a fine-grained application is
+ * prefered in order to benefit from progressive rendering of the browser view.
+ *
+ * `ngCloak` works in cooperation with a css rule that is embedded within `angular.js` and
+ *  `angular.min.js` files. Following is the css rule:
+ *
+ * <pre>
+ * [ng\:cloak], [ng-cloak], [data-ng-cloak], [x-ng-cloak], .ng-cloak, .x-ng-cloak {
+ *   display: none !important;
+ * }
+ * </pre>
+ *
+ * When this css rule is loaded by the browser, all html elements (including their children) that
+ * are tagged with the `ng-cloak` directive are hidden. When Angular comes across this directive
+ * during the compilation of the template it deletes the `ngCloak` element attribute, which
+ * makes the compiled element visible.
+ *
+ * For the best result, `angular.js` script must be loaded in the head section of the html file;
+ * alternatively, the css rule (above) must be included in the external stylesheet of the
+ * application.
+ *
+ * Legacy browsers, like IE7, do not provide attribute selector support (added in CSS 2.1) so they
+ * cannot match the `[ng\:cloak]` selector. To work around this limitation, you must add the css
+ * class `ngCloak` in addition to `ngCloak` directive as shown in the example below.
+ *
+ * @element ANY
+ *
+ * @example
+   <doc:example>
+     <doc:source>
+        <div id="template1" ng-cloak>{{ 'hello' }}</div>
+        <div id="template2" ng-cloak class="ng-cloak">{{ 'hello IE7' }}</div>

+ * @ngdoc directive
+ * @name ng.directive:ngController
+ *
+ * @description
+ * The `ngController` directive assigns behavior to a scope. This is a key aspect of how angular
+ * supports the principles behind the Model-View-Controller design pattern.
+ *
+ * MVC components in angular:
+ *
+ * * Model — The Model is data in scope properties; scopes are attached to the DOM.
+ * * View — The template (HTML with data bindings) is rendered into the View.
+ * * Controller — The `ngController` directive specifies a Controller class; the class has
+ *   methods that typically express the business logic behind the application.
+ *
+ * Note that an alternative way to define controllers is via the {@link ng.$route $route} service.
+ *
+ * @element ANY
+ * @scope
+ * @param {expression} ngController Name of a globally accessible constructor function or an
+ *     {@link guide/expression expression} that on the current scope evaluates to a
+ *     constructor function.
+ *
+ * @example
+ * Here is a simple form for editing user contact information. Adding, removing, clearing, and
+ * greeting are methods declared on the $scope by the controller (see source tab). These methods can
+ * easily be called from the angular markup. Notice that any changes to the data are automatically
+ * reflected in the View without the need for a manual update.

+ * @ngdoc directive
+ * @name ng.directive:ngPluralize
+ * @restrict EA
+ *
+ * @description
+ * # Overview
+ * `ngPluralize` is a directive that displays messages according to en-US localization rules.
+ * These rules are bundled with angular.js, but can be overridden
+ * (see {@link guide/i18n Angular i18n} dev guide). You configure ngPluralize directive
+ * by specifying the mappings between
+ * {@link http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_ru...
+ * plural categories} and the strings to be displayed.
+ *
+ * # Plural categories and explicit number rules
+ * There are two
+ * {@link http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_ru...
+ * plural categories} in Angular's default en-US locale: "one" and "other".
+ *
+ * While a pural category may match many numbers (for example, in en-US locale, "other" can match
+ * any number that is not 1), an explicit number rule can only match one number. For example, the
+ * explicit number rule for "3" matches the number 3. There are examples of plural categories
+ * and explicit number rules throughout the rest of this documentation.
+ *
+ * # Configuring ngPluralize
+ * You configure ngPluralize by providing 2 attributes: `count` and `when`.
+ * You can also provide an optional attribute, `offset`.
+ *
+ * The value of the `count` attribute can be either a string or an {@link guide/expression
+ * Angular expression}; these are evaluated on the current scope for its bound value.
+ *
+ * The `when` attribute specifies the mappings between plural categories and the actual
+ * string to be displayed. The value of the attribute should be a JSON object.
+ *
+ * The following example shows how to configure ngPluralize:
+ *
+ * <pre>
+ * <ng-pluralize count="personCount"
+                 when="{'0': 'Nobody is viewing.',
+ *                      'one': '1 person is viewing.',
+ *                      'other': '{} people are viewing.'}">
+ * </ng-pluralize>
+ *</pre>
+ *
+ * In the example, `"0: Nobody is viewing."` is an explicit number rule. If you did not
+ * specify this rule, 0 would be matched to the "other" category and "0 people are viewing"
+ * would be shown instead of "Nobody is viewing". You can specify an explicit number rule for
+ * other numbers, for example 12, so that instead of showing "12 people are viewing", you can
+ * show "a dozen people are viewing".
+ *
+ * You can use a set of closed braces(`{}`) as a placeholder for the number that you want substituted
+ * into pluralized strings. In the previous example, Angular will replace `{}` with
+ * <span ng-non-bindable>`{{personCount}}`</span>. The closed braces `{}` is a placeholder
+ * for <span ng-non-bindable>{{numberExpression}}</span>.
+ *
+ * # Configuring ngPluralize with offset
+ * The `offset` attribute allows further customization of pluralized text, which can result in
+ * a better user experience. For example, instead of the message "4 people are viewing this document",
+ * you might display "John, Kate and 2 others are viewing this document".
+ * The offset attribute allows you to offset a number by any desired value.
+ * Let's take a look at an example:
+ *
+ * <pre>
+ * <ng-pluralize count="personCount" offset=2
+ *               when="{'0': 'Nobody is viewing.',
+ *                      '1': '{{person1}} is viewing.',
+ *                      '2': '{{person1}} and {{person2}} are viewing.',
+ *                      'one': '{{person1}}, {{person2}} and one other person are viewing.',
+ *                      'other': '{{person1}}, {{person2}} and {} other people are viewing.'}">
+ * </ng-pluralize>
+ * </pre>
+ *
+ * Notice that we are still using two plural categories(one, other), but we added
+ * three explicit number rules 0, 1 and 2.
+ * When one person, perhaps John, views the document, "John is viewing" will be shown.
+ * When three people view the document, no explicit number rule is found, so
+ * an offset of 2 is taken off 3, and Angular uses 1 to decide the plural category.
+ * In this case, plural category 'one' is matched and "John, Marry and one other person are viewing"
+ * is shown.
+ *
+ * Note that when you specify offsets, you must provide explicit number rules for
+ * numbers from 0 up to and including the offset. If you use an offset of 3, for example,
+ * you must provide explicit number rules for 0, 1, 2 and 3. You must also provide plural strings for
+ * plural categories "one" and "other".
+ *
+ * @param {string|expression} count The variable to be bounded to.
+ * @param {string} when The mapping between plural category to its correspoding strings.
+ * @param {number=} offset Offset to deduct from the total number.
+ *
+ * @example
+    <doc:example>
+      <doc:source>
+        <script>
+          function Ctrl($scope) {
+            $scope.person1 = 'Igor';

+ * The `ngRepeat` directive instantiates a template once per item from a collection. Each template
+ * instance gets its own scope, where the given loop variable is set to the current collection item,
+ * and `$index` is set to the item index or key.
+ *
+ * Special properties are exposed on the local scope of each template instance, including:
+ *
+ *   * `$index` – `{number}` – iterator offset of the repeated element (0..length-1)
+ *   * `$first` – `{boolean}` – true if the repeated element is first in the iterator.
+ *   * `$middle` – `{boolean}` – true if the repeated element is between the first and last in the iterator.
+ *   * `$last` – `{boolean}` – true if the repeated element is last in the iterator.
+ *
+ *
+ * @element ANY
+ * @scope
+ * @priority 1000
+ * @param {repeat_expression} ngRepeat The expression indicating how to enumerate a collection. Two
+ *   formats are currently supported:
+ *
+ *   * `variable in expression` – where variable is the user defined loop variable and `expression`
+ *     is a scope expression giving the collection to enumerate.
+ *
+ *     For example: `track in cd.tracks`.
+ *
+ *   * `(key, value) in expression` – where `key` and `value` can be any user defined identifiers,
+ *     and `expression` is the scope expression giving the collection to enumerate.
+ *
+ *     For example: `(name, age) in {'adam':10, 'amalie':12}`.
+ *
+ * @example
+ * This example initializes the scope to a list of names and
+ * then uses `ngRepeat` to display every person:

+ * Optionally `ngOptions` attribute can be used to dynamically generate a list of `<option>`
+ * elements for a `<select>` element using an array or an object obtained by evaluating the
+ * `ngOptions` expression.
+ *
+ * When an item in the `<select>` menu is selected, the value of array element or object property
+ * represented by the selected option will be bound to the model identified by the `ngModel`
+ * directive of the parent select element.
+ *
+ * Optionally, a single hard-coded `<option>` element, with the value set to an empty string, can
+ * be nested into the `<select>` element. This element will then represent `null` or "not selected"
+ * option. See example below for demonstration.
+ *
+ * Note: `ngOptions` provides iterator facility for `<option>` element which should be used instead
+ * of {@link ng.directive:ngRepeat ngRepeat} when you want the
+ * `select` model to be bound to a non-string value. This is because an option element can currently
+ * be bound to string values only.
+ *
+ * @param {string} ngModel Assignable angular expression to data-bind to.
+ * @param {string=} name Property name of the form under which the control is published.
+ * @param {string=} required The control is considered valid only if value is entered.
+ * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
+ *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
+ *    `required` when you want to data-bind to the `required` attribute.
+ * @param {comprehension_expression=} ngOptions in one of the following forms:
+ *
+ *   * for array data sources:
+ *     * `label` **`for`** `value` **`in`** `array`
+ *     * `select` **`as`** `label` **`for`** `value` **`in`** `array`
+ *     * `label`  **`group by`** `group` **`for`** `value` **`in`** `array`
+ *     * `select` **`as`** `label` **`group by`** `group` **`for`** `value` **`in`** `array`
+ *   * for object data sources:
+ *     * `label` **`for (`**`key` **`,`** `value`**`) in`** `object`
+ *     * `select` **`as`** `label` **`for (`**`key` **`,`** `value`**`) in`** `object`
+ *     * `label` **`group by`** `group` **`for (`**`key`**`,`** `value`**`) in`** `object`
+ *     * `select` **`as`** `label` **`group by`** `group`
+ *         **`for` `(`**`key`**`,`** `value`**`) in`** `object`
+ *
+ * Where:
+ *
+ *   * `array` / `object`: an expression which evaluates to an array / object to iterate over.
+ *   * `value`: local variable which will refer to each item in the `array` or each property value
+ *      of `object` during iteration.
+ *   * `key`: local variable which will refer to a property name in `object` during iteration.
+ *   * `label`: The result of this expression will be the label for `<option>` element. The
+ *     `expression` will most likely refer to the `value` variable (e.g. `value.propertyName`).
+ *   * `select`: The result of this expression will be bound to the model of the parent `<select>`
+ *      element. If not specified, `select` expression will default to `value`.
+ *   * `group`: The result of this expression will be used to group options using the `<optgroup>`
+ *      DOM element.
