 ***************************************************************************
 *
 * $Log: StKinkVertex.h,v $
 * Revision 2.9  2009/11/23 16:34:06  fisyak
 * Cleanup, remove dependence on dst tables, clean up software monitors
 *
 * Revision 2.8  2004/07/15 16:36:24  ullrich
 * Removed all clone() declerations and definitions. Use StObject::clone() only.
 *
 * Revision 2.7  2002/02/22 22:56:48  jeromel
 * Doxygen basic documentation in all header files. None of this is required
 * for QM production.
 *
 * Revision 2.6  2001/05/30 17:45:54  perev
 * StEvent branching
 *
 * Revision 2.5  2001/04/05 04:00:38  ullrich
 * Replaced all (U)Long_t by (U)Int_t and all redundant ROOT typedefs.
 *
 * Revision 2.4  2001/03/24 03:34:52  perev
 * clone() -> clone() const
 *
 * Revision 2.3  1999/11/04 16:33:26  ullrich
 * Fixed wrong option to ClassDef macro.
 *
 * Revision 2.2  1999/10/28 22:25:56  ullrich
 * Adapted new StArray version. First version to compile on Linux and Sun.
 *
 * Revision 2.1  1999/10/13 19:43:22  ullrich
 * Initial Revision
