 *
 * $Log: StMuDstMaker.h,v $
 * Revision 1.66  2021/05/11 19:40:43  jdb
 * StETofHeader update from philipp W. modified classes to include the front-end missmatch pattern
 *
 * Revision 1.65  2019/02/21 14:00:02  jdb

 *
 * Revision 1.64  2019/02/21 13:32:54  jdb
 * Inclusion of ETOF MuDst code. This code adds support for the full set of ETOF data which includes EtofDigi, EtofHit, EtofHeader. The code essentially copies similar structures from StEvent and additionally rebuilds the maps between Digis and Hits. Accessor methods are added based on the pattern from BTOF to provide access to data at various levels. The code for accessing the PID traits provided by ETOF is also provided
 *
 * Revision 1.63  2018/03/15 22:00:35  smirnovd

 * http://www.star.bnl.gov/cgi-bin/cvsweb.cgi/StRoot/StMuDSTMaker/COMMON/StMuDstMaker.h.diff?r1=1.35&r2=1.36
 * but re-comitting without the mess up (seems like source and h were merged)
 *
 * Revision 1.35  2004/09/18 01:28:18  jeromel
 * *** empty log message ***

 * after tof createevent fix by Xin
 *
 * Revision 1.29  2004/04/09 03:36:15  jeromel
 * Removed TOF support entirely for now as we need a working version ... Will
 * revisit later.
 *
 * Revision 1.28  2004/04/02 03:24:54  jeromel
 * Changes implements PMD and TOF.  TOF is clearly incomplete.
 *
 * Revision 1.27  2004/02/17 04:56:36  jeromel
 * Extended help, added crs support, restored __GNUC__ for PRETTY_FUNCTION(checked once
 * more and yes, it is ONLY defined in GCC and so is __FUCTION__),  use of a consistent
 * internal __PRETTYF__, return NULL if no case selected (+message) and protected against
 * NULL mChain.
 *
 * Revision 1.26  2003/11/09 01:02:59  perev
 * more sofisticated clear() to fix leaks
 *
 * Revision 1.25  2003/10/30 20:08:13  perev

 * A few problems hopefully fixed i.e. one constructor lacked zeroing
 * emcArrays were not  zeroed, mStMuDst not zeroed.
 * For maintainability zeroArrays() added.
 *
 * Revision 1.21  2003/09/02 17:58:44  perev

 * Modifications made to account for the new location of the PIDTable file.

 * file).
 *
 * Revision 1.18  2003/01/29 03:04:57  laue
