14  * Revision 1.5 2000/10/09 21:56:16 laue
15  * Helens new cuts
16  *
17  * Revision 1.4 2000/01/25 17:35:02 laue
18  * I. In order to run the stand alone version of the StHbtMaker the following
19  * changes have been done:
20  * a) all ClassDefs and ClassImps have been put into #ifdef __ROOT__ statements
21  * b) unnecessary includes of StMaker.h have been removed
22  * c) the subdirectory StHbtMaker/doc/Make has been created including everything
23  * needed for the stand alone version
24  *
25  * II. To reduce the amount of compiler warning
26  * a) some variables have been type casted
27  * b) some destructors have been declared as virtual
28  *
29  * Revision 1.3 1999/10/15 01:57:02 lisa
30  * Important enhancement of StHbtMaker - implement Franks CutMonitors
31  * ----------------------------------------------------------
32  * This means 3 new files in Infrastructure area (CutMonitor),
33  * several specific CutMonitor classes in the Cut area
34  * and a new base class in the Base area (StHbtCutMonitor).
35  * This means also changing all Cut Base class header files from .hh to .h
36  * so we have access to CutMonitor methods from Cint command line.
37  * This last means
38  * 1) files which include these header files are slightly modified
39  * 2) a side benefit: the TrackCuts and V0Cuts no longer need
40  * a SetMass() implementation in each Cut class, which was stupid.
41  * Also:
42  * -----
43  * Include Franks StHbtAssociationReader
44  * ** None of these changes should affect any user **
45  *
46  * Revision 1.2 1999/10/05 11:37:40 lisa
47  * Helens realistic V0Cut and Franks memory-sealed McReader
48  *
49  * Revision 1.1 1999/09/23 23:28:03 lisa
50  * add helensV0Cut AND rename mikes and franks ParticleCuts to TrackCuts AND update documentation
51  *
