function [H] = HShannon_KDP_estimation(Y,co)
%Estimates the Shannon differential entropy (H) of Y using k-d partitioning.
%
%We use the naming convention 'H<name>_estimation' to ease embedding new entropy estimation methods.
%
%INPUT:
%   Y: Y(:,t) is the t^th sample.
%  co: entropy estimator object.
