function b = relabel(a,newlab)
% B = relabel(A,newlab)

% Rename the labels in dataset A to newlab. Of course, the length of
% newlab should be equal to the lablist of dataset A. The first class
% from the lablist will get the first label in newlab. 
%
% This function is useful when from a dataset A, several classes are
% to be renamed to 'target' and the rest to outlier class. If just a
% single class should be named 'target' then target_class or oc_set
% should be used.
