function [co] = HTsallis_HRenyi_initialization(mult)
%Initialization of the meta Tsallis entropy estimator defined according to the relation: H_{T,alpha} = (e^{H_{R,alpha}(1-alpha)} - 1) / (1-alpha), where H_{T,alpha} and H_{R,alpha} denotes the Tsallis and the Renyi entropy, respectively.
%   1)The estimator is treated as a cost object (co).
%   2)We make use of the naming convention 'H<name>_initialization', to ease embedding new entropy estimation methods.
%   mult: is a multiplicative constant relevant (needed) in the estimation; '=1' means yes, '=0' no.
%   co: cost object (structure).
