 * Description: part of STAR HBT Framework: StHbtMaker package
 *      This is the Class for Analysis objects.  Each of the simultaneous
 *      Analyses running should have one of these instantiated.  They link
 *      into the Manager in an Analysis Collection.

 *
 * $Log: StHbtSplitEvalAnalysis.h,v $
 * Revision 1.2  2001/11/05 14:11:20  lisa
 * small modifications to Splitting Analysis class and macro
 *
 * Revision 1.1  2000/08/15 22:18:47  lisa
 * Add a special HbtAnalysis class that estimates amount of splitting and add a macro to use it
 *
 * Revision 1.12  2000/06/15 18:54:08  willson
 * Methods to access cuts and correlation functions moved to derived analysis
 * classes.
 *
 * Revision 1.11  2000/05/11 21:18:56  willson
 * Removed StHbtThreeParticleCorrFctn's...put methods in StHbtCorrFctn
 * Some methods in derived analysis classes moved to base analysis class
 *
 * Revision 1.10  2000/04/03 16:21:50  laue
 * some include files changed
 * Multi track cut added
 *
 * Revision 1.9  2000/03/17 17:23:05  laue
 * Roberts new three particle correlations implemented.
 *
 * Revision 1.8  2000/03/16 02:07:04  laue
 * Copy constructor added to StHbtSplitEvalAnalysis (only known cuts, corrfctn).
 *
 * StHbtBinaryReader can now derive filename from StIOMaker and read a list
 * of files.
 *
 * StHbtManager now holds a collection of StHbtEventWriters (multiple writes
 * possible now)
 *
 * Revision 1.7  2000/02/13 17:17:12  laue
 * Calls to the EventBegin() and EventEnd() functions implemented
 * The actual analysis is moved from StHbtManager to StHbtSplitEvalAnalysis
 *
 * Revision 1.6  2000/01/25 17:35:17  laue
 * I. In order to run the stand alone version of the StHbtMaker the following
 * changes have been done:
 * a) all ClassDefs and ClassImps have been put into #ifdef __ROOT__ statements
 * b) unnecessary includes of StMaker.h have been removed
 * c) the subdirectory StHbtMaker/doc/Make has been created including everything
 * needed for the stand alone version
 *
 * II. To reduce the amount of compiler warning
 * a) some variables have been type casted
 * b) some destructors have been declared as virtual
 *
 * Revision 1.5  1999/12/03 22:24:36  lisa
 * (1) make Cuts and CorrFctns point back to parent Analysis (as well as other way). (2) Accommodate new PidTraits mechanism
 *
 * Revision 1.4  1999/10/15 01:57:23  lisa
 * Important enhancement of StHbtMaker - implement Franks CutMonitors
 * ----------------------------------------------------------
 * This means 3 new files in Infrastructure area (CutMonitor),
 * several specific CutMonitor classes in the Cut area
 * and a new base class in the Base area (StHbtCutMonitor).
 * This means also changing all Cut Base class header files from .hh to .h
 * so we have access to CutMonitor methods from Cint command line.
 * This last means
 * 1) files which include these header files are slightly modified
 * 2) a side benefit: the TrackCuts and V0Cuts no longer need
 * a SetMass() implementation in each Cut class, which was stupid.
 * Also:
 * -----
 * Include Franks StHbtAssociationReader
 * ** None of these changes should affect any user **
 *
 * Revision 1.3  1999/10/04 15:38:56  lisa
 * include Franks new accessor methods StHbtSplitEvalAnalysis::CorrFctn and StHbtManager::Analysis as well as McEvent example macro
 *
 * Revision 1.2  1999/07/06 22:33:22  lisa
 * Adjusted all to work in pro and new - dev itself is broken
 *
 * Revision 1.1.1.1  1999/06/29 16:02:57  lisa
 * Installation of StHbtMaker
 *
