00008  * Description: part of STAR HBT Framework: StHbtMaker package
00009  *   HbtEvent is the "transient microDST"  Objects of this class are
00010  *   generated from the input data by a Reader, and then presented to
00011  *   the Cuts of the various active Analyses.

00030  * Modified fiels:
00031  *   CTH.hh : new constructor added
00032  *   StHbtEvent, StHbtKink, StHbtTrack : constructors from the persistent

00044  * Adding B-field, run number, and improved reaction plane functionality
00045  *
00046  * Revision 1.12  2001/05/25 23:23:59  lisa
00047  * Added in StHbtKink stuff
00048  *
00049  * Revision 1.11  2001/05/15 15:30:16  rcwells

00063  * franksTrackCut changed. If mCharge is set to '0' there will be no cut
00064  * on charge. This is important for front-loaded cuts.
00065  *
00066  * copy constructor implemented for StHbtEvent, StHbtTrack and StHbtV0.
00067  *
00068  * franks1HistoD.cxx franks1HistoD.h franks2HistoD.cxx franks2HistoD.h
00069  * removed. We can now (CC5 on Solaris) use the versions (no D)
