function [co] = KJS_DJS_initialization(mult)
%Initialization of the Jensen-Shannon kernel estimator defined according to the relation: K_JS(f_1,f_2) = log(2) - D_JS(f_1,f_2), where D_JS is the Jensen-Shannon divergence.
%
%Note:
% 1)The estimator is treated as a cost object (co).
% 2)We use the naming convention 'K_initialization' to ease embedding new estimators for kernels on distributions.
% 3)This is a meta method: the Jensen-Shannon divergence estimator can arbitrary.
%
%INPUT:
% mult: is a multiplicative constant relevant (needed) in the estimation; '=1' means yes, '=0' no.
%OUTPUT:
% co: cost object (structure).
