 * $Log: StHelixModel.h,v $
 * Revision 2.10  2009/11/23 16:34:06  fisyak
 * Cleanup, remove dependence on dst tables, clean up software monitors
 *
 * Revision 2.9  2004/07/15 16:36:24  ullrich
 * Removed all clone() declerations and definitions. Use StObject::clone() only.
 *
 * Revision 2.8  2003/04/09 17:59:39  genevb
 * Add setMomentum function
 *
 * Revision 2.7  2002/11/26 02:19:11  perev
 * StEventMaker ITTF modif
 *
 * Revision 2.6  2002/02/22 22:56:48  jeromel
 * Doxygen basic documentation in all header files. None of this is required
 * for QM production.
 *
 * Revision 2.5  2001/07/17 22:23:30  ullrich
 * Added helicity to track geometry.
 *
 * Revision 2.4  2001/04/05 04:00:37  ullrich
 * Replaced all (U)Long_t by (U)Int_t and all redundant ROOT typedefs.
 *
 * Revision 2.3  2001/03/24 03:34:49  perev
 * clone() -> clone() const
 *
 * Revision 2.2  1999/10/28 22:25:45  ullrich
 * Adapted new StArray version. First version to compile on Linux and Sun.
 *
 * Revision 2.1  1999/10/13 19:43:20  ullrich
 * Initial Revision
