Classifier

 function [cl] = classifier(pos, neg)
 constructor for the classifier class
   The classifier class is a base class for all classifier. It declares
   the interface for any classifer. All the methods are to implemented by
   the descendent classifier classes

   Inputs:
       nc: number of classes
