These classifiers are designed to classify numerical data, assigning a label to a feature vector.

Normal classes:

ClassifyVectorC	Generic classifier.
DesignClassifyVectorC	Abstract classifer designer.
DesignDiscriminantFunctionC	Design a discriminat function classifier.
DesignKNearestNeighbourC	Design a discriminat function classifier.
ClassifyKNearestNeighbourC	k nearest neighbours classifier.
ClassifyAverageNearestNeighbourC	ClassifyAverage k nearest neighbour classifier.
