 * $Log: StFtpcHit.cxx,v $
 * Revision 2.13  2009/11/23 16:34:06  fisyak
 * Cleanup, remove dependence on dst tables, clean up software monitors
 *
 * Revision 2.12  2004/09/15 17:20:54  ullrich
 * Updated from Janet (unpacking of bits).
 *
 * Revision 2.11  2004/07/15 16:36:24  ullrich
 * Removed all clone() declerations and definitions. Use StObject::clone() only.
 *
 * Revision 2.10  2004/05/07 15:05:28  calderon
 * Adding constructor based on StFtpcPoint from Markus.
 *
 * Revision 2.9  2004/04/08 19:02:33  ullrich
 * Added additional data member and access methods to hold the position in
 * pad and time units including their std deviation. Constructors updated.
 *
 * Revision 2.8  2001/04/05 04:00:50  ullrich
 * Replaced all (U)Long_t by (U)Int_t and all redundant ROOT typedefs.
 *
 * Revision 2.7  2001/03/24 03:34:46  perev
 * clone() -> clone() const
 *
 * Revision 2.6  2000/06/01 21:38:49  ullrich
 * Added member mFlag and access member flag() and setFlag().
 *
 * Revision 2.5  1999/12/13 20:16:12  ullrich
 * Changed numbering scheme for hw_position unpack methods (STAR conventions).
 *
 * Revision 2.4  1999/12/06 18:28:21  ullrich
 * Changed method names xxxInCluster to xxxInHit
 *
 * Revision 2.3  1999/11/09 19:35:09  ullrich
 * Memory now allocated using StMemoryPool via overloaded new/delete
 *
 * Revision 2.2  1999/11/04 21:40:49  ullrich
 * Added missing default constructor
 *
 * Revision 2.1  1999/10/28 22:25:16  ullrich
