/**
 * The marker interface implemented by all statistic observer classes.
 * 
 * A statistic observer presents methods used to update a statistic.  There are
 * two general classes of observer implementations:
 * 

 *   Initial observers are called by product code in order to record the
 * occurrence of a product related 'event'
 *   Derived observers are called by other observers with then intention of
 * tracking higher order statistics.
