%% Test notes
%% % *Weak classifiers: Tree,Knn,Discriminant
    %* Tweak Nlearners
    %* other params (
    %* for Bag: try 'regression' too
    %* for Boost: try different boosts
    %* for Stacking ?:
   %For table: use start=tic; time=toc(start); and Evaluate fcn (needs modifiyng for multi class)
        % So we have same data to put on table
   %plots: dimention vs. class , 2-dimension vs. class rtc.
