 *
 * $Log: StMuDst.cxx,v $
 * Revision 1.70  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 1.69  2018/02/27 04:11:57  jdb
 * Added epdArrays
 *
 * Revision 1.68  2017/01/19 23:03:19  smirnovd
 * Copy previously missing values in StMuTrack to StTrack conversion
 *
 * Revision 1.67  2017/01/19 23:03:13  smirnovd
 * Promise to not modify original StMuTrack when converting to StTrack
 *
 * Revision 1.66  2016/10/01 21:23:25  jdb
 * Changed default vertex index to -2. Recently changed it to -1 which caused unintended segfault since -1 is used as a special case value in other parts of the code.
 *
 * Revision 1.65  2016/09/30 01:06:40  jdb
 * initialize mCurrVertexId to -1 (was 0) so that when it is set the first time it will always cause the needed function call to collectVertexTracks().
 *
 * Revision 1.64  2014/06/25 01:26:39  jdb
 * Updated StMuDst::setMtdArray() and reset the MTD header. Needed for Run12 UU data where only the muMtdCollection is available.
 *
 * Revision 1.63  2014/05/16 15:06:45  jdb
 * chaned StMuDst{.h,.cxx} to add setMtdArray function
 *
 * Revision 1.62  2014/04/15 04:48:47  jdb
 * Changed mtdArrays[muBTofHit] to mtdArrays[muMTDHit] in StMuDst.cxx in function fixMtdTrackIndices
 *
 * Revision 1.61  2014/03/03 23:11:46  jdb
 * Added Rongrongs changes to StMuDst.cxx and StMuMtdHit.{cxx,h} for mtd tracks
 *
 * Revision 1.60  2013/12/04 19:56:32  jdb

 * Revision 1.42  2007/09/18 02:29:57  mvl
 * Added basic printing functionality. For convenience and to assist data consistency checks
 *
 * Revision 1.41  2007/05/16 18:50:49  mvl
 * Cleanup of output. Replaced cout with LOG_INFO etc.
 *
 * Revision 1.40  2007/04/20 06:25:21  mvl
 * Removed Q-vectors (will implement utility class).
 * Added Vpd info.
 *
 * Revision 1.39  2006/02/07 03:26:08  mvl
 * Changed createStEvent (use by MuDst2StEventmaker) to only copy primary tracks
 * that belong to the first primary vertex. This prevents segvio for events with
 * multiple primary vertices.
 *
 * Revision 1.38  2005/12/13 03:12:13  mvl
 * Changes to StMuDst2StEventMaker (code in StMuDst) and StMuDstFilterMaker
 * to no longer rely on track keys for matching global and primary tracks.
 * This was needed because track keys are not guaranteed to be unique anymore.
 *
 * Revision 1.37  2005/08/19 19:46:05  mvl
 * Further updates for multiple vertices. The main changes are:
 * 1) StMudst::primaryTracks() now returns a list (TObjArray*) of tracks
 *    belonging to the 'current' primary vertex. The index number of the
 *    'current' vertex can be set using StMuDst::setCurrentVertex().
 *    This also affects StMuDst::primaryTracks(int i) and
 *    StMuDst::numberOfprimaryTracks().
 * 2) refMult is now stored for all vertices, in StMuPrimaryVertex. The
 *    obvious way to access these numbers is from the StMuprimaryVertex structures,
 *    but for ebakcward compatibility a function is provided in StMuEvent as well
 *    (this is the only function taht works for existing MuDst)
 *
 * As an aside, I've also changes the internals of StMuDst::createStEvent and
 * StMuDst::fixTrackIndices() to be able to deal with a larger range of index numbers for tracks as generated by Ittf.
 *
 * BIG FAT WARNING: StMudst2StEventMaker and StMuDstFilterMaker
 * do not fully support the multiple vertex functionality yet.
 *
 * Revision 1.36  2005/05/20 20:30:35  mvl
 * More fixed to StMuDst::fixTrackIndices(). The bug afafcets only few tracks
 * for events with many tracks, so most people will not be much affected by it.
 * After heavy filtering with StMuDstFilterMaker (many fewer tracks than tack-ids)
 * the bug became apparent.
 *
 * Revision 1.35  2005/05/18 20:56:57  mvl
 * Fixed inconsistency in fixTrackIndices (pointed out by Alex Suaide):
 * now using the TClonesArray that are passed to the function, instead of the
 * ones in StMuDst.
 *
 * Revision 1.34  2005/04/12 21:56:29  mvl
 * Changes by Xin Dong for year-5 TOF data format: extra TClonesArray and routines to fill it from StEvent (StTofRawData).
 *
 * Revision 1.33  2004/10/28 00:11:33  mvl
 * Added stuff to support ezTree mode of MuDstMaker.
