// Description:
//  Class HepHistID :
//  This class allows ID numbers, ID strings or both to be used
//  to uniquely identify histograms.  The actual use of this
//  class depends on the concrete package that implements HepTuple
//
//
// Environment:
//  Software developed for the BaBar Detector at the SLAC B-Factory.
