/***************************************************************************
 *
 * $Log: StMuDst2StEventMaker.cxx,v $
 * Revision 1.13  2007/05/16 18:50:49  mvl
 * Cleanup of output. Replaced cout with LOG_INFO etc.
 *
 * Revision 1.12  2004/10/21 02:59:01  mvl
 * Now get MuDst from GetInputDS, instead of StMuDSTMaker
 *
 * Revision 1.11  2004/04/15 00:24:07  perev
 * GetEvtHddr() used now
 *
 * Revision 1.10  2003/10/14 14:35:53  laue
 * Alex Suaide EMC updates
 *
 * Revision 1.9  2003/09/17 02:54:37  jeromel
 * Name clash. Added warning in case this happens in future
 *
 * Revision 1.8  2003/09/12 21:32:40  jeromel
 * Bug fix : zeroing missing
 *
 * Revision 1.7  2003/09/07 03:49:03  perev
 * gcc 3.2 + WarnOff
 *
 * Revision 1.6  2003/08/29 14:54:00  laue
 * Commented out printing of the trigger ids and the (test)-loop over the tracks.
 *
 * Revision 1.5  2003/08/28 13:01:45  laue
 * now passing proper maker name to the call of the StMaker(name) constructor
 *
 * Revision 1.4  2003/08/04 14:38:10  laue
 * Alex Suaide's updated for the EMC. Now EEMC is included.
 *
 * Revision 1.3  2003/04/15 18:48:35  laue
 * Minor changes to be able to filter MuDst.root files and an example
 * how to do this. The StMuDstFilterMaker is just an example, it has to be
 * customized (spoilers, chrome weels, etc.) by the user.
 *
 * Revision 1.2  2003/03/19 18:58:04  laue
 * StMuChainMaker: updates for moved file catalog
 * StTriggerIdCollection added to the createStEvent function in StMuDst.cxx
 *
 * Revision 1.1  2003/01/09 18:59:45  laue
 * initial check in of new EMC classes and the changes required
 *
 * Revision 1.15  2002/11/08 14:18:59  laue
 *
