 * $Log: StEStructEventReader.h,v $
 * Revision 1.3  2012/11/16 21:19:06  prindle
 * Moved EventCuts, TrackCuts to EventReader. Affects most readers.
 * Added support to write and read EStructEvents.
 * Cuts: 3D histo support, switch to control filling of histogram for reading EStructEvents
 * EventCuts: A few new cuts
 * MuDstReader: Add 2D to some histograms, treat ToFCut, PrimaryCuts, VertexRadius histograms like other cut histograms.
 * QAHists: Add refMult
 * TrackCuts: Add some hijing cuts.
 *
 * Revision 1.2  2006/04/04 22:05:05  porter
 * a handful of changes:
 *  - changed the StEStructAnalysisMaker to contain 1 reader not a list of readers
 *  - added StEStructQAHists object to contain histograms that did exist in macros or elsewhere
 *  - made centrality event cut taken from StEStructCentrality singleton
 *  - put in  ability to get any max,min val from the cut class - one must call setRange in class
 *
 * Revision 1.1  2003/10/15 18:20:32  porter
 * initial check in of Estruct Analysis maker codes.
 *
