 *
 * $Log: StRichPid.cxx,v $
 * Revision 2.6  2001/04/05 04:00:53  ullrich
 * Replaced all (U)Long_t by (U)Int_t and all redundant ROOT typedefs.
 *
 * Revision 2.5  2000/12/08 03:50:31  ullrich
 * Removed compiler warning (signed/unsigned comparison).
 *
 * Revision 2.4  2000/11/25 11:51:49  lasiuk
 * remove D vector and replace with a container of StRichPhotonInfo
 *
 * Revision 2.3  2000/11/21 19:47:33  lasiuk
 * add the d information for each hit
 * use the TArrayF
 *
 * Revision 2.2  2000/11/01 16:45:43  lasiuk
 * Keep the pointers to the hits that are associated with the track
 * in order to use the bit flag information.  These are kept
 * in an StPtrVec (does not own the hits)  The PDG encoded number
 * is kept as a data member now
 *
 * Revision 2.1  2000/09/28 10:53:56  ullrich
 * Initial Revision.
