/**
  * Interface for a set of attribute value pairs, including the
  * classification.
  *<p>
  * When you think about it, the classification of a set of instances
  * and the instances themselves are separate. For example, a different
  * representation of the stream still has the same class. 
  * This technique of having a representation for streams and classifications
  * separately simplifies representation conversion (which, as you can guess, 
  * we do in several places in the code, since representation conversion
  * is the basis of the learning algorithm). 
  * <p>
  * So this class acts as little more than a wrapper of two classes, one which 
  * is the ClassificationVecI and the other which is the StreamAttValVecI. 
  * <p>
  * Note that the classification vector and the vector of attribute-value streams 
  * should be of equal size ... otherwise ... evil things will happen.
