function [co] = co_initialization(cost_type,cost_name,mult)
%Returns a cost object (co), i.e, an entropy/mutual information estimator.
%
%In case of an entropy based ISA formulation we will need an entropy estimator; 
%in case of a mutual information based ISA formulation we will need a mutual information estimator.
%
%INPUT:
%   mult: is a multiplicative constant relevant (needed) in the estimation; '=1' means yes, '=0' no.
