public abstract class StatsMatrix
This class describes a special kind of integer matrix which is used for keeping stats on how well a predictive procedure is performing. This is useful only for discrete predictions; i.e. there are N categories something can be in, and you want to predict it as one of these N (or at least eliminate some of the choices). There are 2 types of these matrices, called "similarity matrices" and "correctness matrices"; this is an abstract class that includes both.
