 * $Log: StSsdHit.cxx,v $
 * Revision 2.14  2009/11/23 22:20:51  ullrich
 * Minor cleanup performed, fixed compiler warnings.
 *
 * Revision 2.13  2009/11/23 16:34:07  fisyak
 * Cleanup, remove dependence on dst tables, clean up software monitors
 *
 * Revision 2.12  2009/11/10 00:40:17  ullrich
 * Changed print-out format.
 *
 * Revision 2.11  2006/04/27 21:58:53  ullrich
 * Added data member and methods to deal with local positions.
 *
 * Revision 2.10  2005/12/19 19:24:10  ullrich
 * Applied patch by A. Kiesel to fix tp correct decoding of hardware info.
 *
 * Revision 2.9  2004/07/15 16:36:25  ullrich
 * Removed all clone() declerations and definitions. Use StObject::clone() only.
 *
 * Revision 2.8  2001/04/05 04:00:55  ullrich
 * Replaced all (U)Long_t by (U)Int_t and all redundant ROOT typedefs.
 *

 *
 * Revision 2.6  2000/06/01 21:39:00  ullrich
 * Added member mFlag and access member flag() and setFlag().
 *
 * Revision 2.5  2000/01/05 16:05:37  ullrich
 * Updated for actual use in StEvent. Unpacking changed.
 *
 * Revision 2.4  1999/11/09 19:35:15  ullrich
 * Memory now allocated using StMemoryPool via overloaded new/delete
 *
 * Revision 2.3  1999/11/04 21:40:52  ullrich
