function 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.
