%Initialization of the power spectral density representation and Szego's theorem based Kullback-Leibler divergence estimator.
%   1)The estimator is treated as a cost object (co).
%   2)We use the naming convention 'D<name>_initialization' to ease embedding new divergence estimation methods.
%   mult: is a multiplicative constant relevant (needed) in the estimation; '=1' means yes, '=0' no.
%   post_init: {field_name1,field_value1,field_name2,field_value2,...}; cell array containing the names and the values of the cost object fields that are to be used
%   (instead of their default values). For further details, see 'post_initialization.m'.
%   co: cost object (structure).
