用于multivariate时间序列分类

/**
  * Interface for a set of attribute value pairs, including the
  * classification.
  *
  * 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).
