%  Find the class assignment of the samples from the likelihoods
%  'likelihoods' an NxD matrix where N is the number of samples and
%  D is the dimension of the feature space. 'likelihoods(i,j)' is
%  the i-th samples likelihood of belonging to class-j.
%
%  'classes' contains the class index of the each sample maximum likelihood
