 *
 * $Log: StGlobalTrack.cxx,v $
 * Revision 2.7  2012/05/07 14:42:57  fisyak
 * Add handilings for Track to Fast Detectors Matching
 *
 * Revision 2.6  2009/11/23 16:34:06  fisyak
 * Cleanup, remove dependence on dst tables, clean up software monitors
 *
 * Revision 2.5  2007/03/20 20:56:19  perev
 * LeakFix StDcaGeometry was not deleted at all
 *
 * Revision 2.4  2006/05/24 17:28:19  ullrich
 * Added track-at-DCA geometry.
 *
 * Revision 2.3  2004/07/15 16:36:24  ullrich
 * Removed all clone() declerations and definitions. Use StObject::clone() only.
 *
 * Revision 2.2  2001/03/24 03:34:47  perev
 * clone() -> clone() const
 *
 * Revision 2.1  1999/10/28 22:25:36  ullrich
