%GENLAB Generate labels for classes
% 
% 	labels = genlab(n,lablist)
% 
% Generates a set of labels as defined by the labellist lablist. n 
% is a vector. The first n(i) labels get the value lablist(i,:). If 
% lablist is omitted labels as '1', '2', ... are used.
% 
% Labels can be used to construct a labelled dataset.
