%MATCHLABLIST Match entries of lablist1 with lablist2
%
%    I = MATCHLABLIST(LABLIST1,LABLIST2)
%
% INPUT
%    LABLIST1  list of class names
%    LABLIST2  list of class names
%
% OUTPUT
%    I         indices for LABLIST1 appearing in LABLIST2
%
% DESCRIPTION
% Find the indices of places where the entries of LABLIST1 appear 
% in LABLIST2, i.e. LABLIST1 = LABLIST2(I).
% Note that this operation is not symmetric, changing the order of
% LABLIST1 and LABLIST2 changes I! 
% I(i) = 0 for labels appearing in LABLIST1 that are not in LABLIST2.
