//  Change names so that every data class has the same format so that
//  we have that down from the very beginning, so that we will not have to
//  worry about that later on.  The affected classes are:
//
//
//          BrRdoBB             ->        BrBbRdo
//          BrRdoZDC            ->        BrZdcRdo
//  	BrTPCCluster	    ->	      BrTpcCluster
//  	BrTPCClusterTable   ->	      BrTpcClusterTable
//
//  Revision 1.1.1.1  2001/06/21 14:55:02  hagel
//  Initial revision of brat2
//
//  Revision 1.3  2001/01/30 10:31:30  pchristi
//  Added const to methods in BrDetectorHit and some utility methods to
//  BrLocalTrack.
//
//  Revision 1.2  1999/12/23 15:58:55  videbaek
//  Enhanched use of ClonesArrays for temporary data. i.e. tracks hits
//  so they become accessible to the outside.
//
//  Revision 1.1  1999/03/07 22:37:38  videbaek
//  Added DetectorHit and BrLocalTrackingModule as a more general way to
//  deal with local tracks and hits. Initial insertion. Not fully debugged.
