14  * $Log: StHbtKink.cc,v $
15  * Revision 1.4 2001/11/14 21:07:21 lisa
16  * Fixed several small things (mostly discarded const) that caused fatal errors with gcc2.95.3
17  *
18  * Revision 1.3 2001/09/05 21:55:23 laue
19  * typo fixed
20  *
21  * Revision 1.2 2001/06/21 19:15:46 laue
22  * Modified fiels:
23  * CTH.hh : new constructor added
24  * StHbtEvent, StHbtKink, StHbtTrack : constructors from the persistent
25  * (TTree) classes added
26  * StHbtLikeSignAnalysis : minor changes, for debugging
27  * StHbtTypes: split into different files
28  * Added files: for the new TTree muDst's
29  * StExceptions.cxx StExceptions.hh StHbtEnumeration.hh
30  * StHbtHelix.hh StHbtHisto.hh StHbtString.hh StHbtTFile.hh
31  * StHbtTTreeEvent.cxx StHbtTTreeEvent.h StHbtTTreeKink.cxx
