// Description:
//      BdbClusteringHint class implementation file. This is the universal 
//  clustering class used by the BaBar persistent classes. It is 
//  customizable via specification of a delegate class.
//
// Environment:
//      Software developed for the BaBar Detector at the SLAC B-Factory.
//
// Author List:
//      David R. Quarrie                Lawrence Berkeley National Laboratory
