_D_e_s_c_r_i_p_t_i_o_n:

     A method to calculate the Akaike information criterion (AIC) of an
     FLModel object from the value of the obtained log-likelihood
     stored in its 'logLik' slot.

_G_e_n_e_r_i_c _f_u_n_c_t_i_o_n:

     AIC(object, k)

     '_o_b_j_e_c_t' : an object of class FLModel or of one that inherits from
          it.

     '_k' : numeric, the "penalty" per parameter to be used; the default
          k = 2 is the classical AIC.

_M_e_t_h_o_d_s:

          with an specified  value for the "penalty".

          with the default  "penalty".
