00101  * $Log: StMuPrimaryVertex.h,v $
00102  * Revision 1.8  2012/05/07 14:47:06  fisyak
00103  * Add handles for track to fast detector matching
00104  *
00105  * Revision 1.7  2011/10/17 00:19:14  fisyak
00106  * Active handing of IdTruth
00107  *
00108  * Revision 1.6  2011/04/08 01:25:51  fisyak
00109  * Add branches for MC track and vertex information, add IdTruth to  tracks and vertices, reserve a possiblity to remove Strange MuDst
00110  *
00111  * Revision 1.5  2009/12/24 21:19:31  tone421
00112  * Added StMuPrimaryVertex::nBTOFMatch()
00113  *
00114  * Revision 1.4  2007/09/18 02:29:58  mvl
00115  * Added basic printing functionality. For convenience and to assist data consistency checks
00116  *
00117  * Revision 1.3  2006/04/25 08:27:43  mvl
00118  * Added members and getters for mean-dip and chisquared value
00119  *
00120  * Revision 1.2  2005/08/19 19:46:05  mvl
00121  * Further updates for multiple vertices. The main changes are:
00122  * 1) StMudst::primaryTracks() now returns a list (TObjArray*) of tracks
00123  *    belonging to the 'current' primary vertex. The index number of the
00124  *    'current' vertex can be set using StMuDst::setCurrentVertex().
00125  *    This also affects StMuDst::primaryTracks(int i) and
00126  *    StMuDst::numberOfprimaryTracks().
00127  * 2) refMult is now stored for all vertices, in StMuPrimaryVertex. The
00128  *    obvious way to access these numbers is from the StMuprimaryVertex structures,
00129  *    but for ebakcward compatibility a function is provided in StMuEvent as well
00130  *    (this is the only function that works for existing MuDst)
00131  *
00132  * As an aside, I've also changes the internals of StMuDst::createStEvent and
00133  * StMuDst::fixTrackIndices() to be able to deal with a larger range of index numbers for tracks as generated by Ittf.
00134  *
00135  * BIG FAT WARNING: StMudst2StEventMaker and StMuDstFilterMaker
00136  * do not fully support the multiple vertex functionality yet.
00137  *
00138  * Revision 1.1  2005/07/15 21:45:09  mvl
00139  * Added support for multiple primary vertices (StMuPrimaryVertex). Track Dcas are now calculated with repect to the first vertex in the list (highest rank), but another vertex number can be specified. Tarcks also store the index of the vertex they belong to (StMuTrack::vertexIndex())
