 * $Log: StMcAnalysisMaker.h,v $
 * Revision 1.12  2015/03/13 18:44:50  perev
 * Roll back
 *
 * Revision 1.10  2014/08/06 11:43:26  jeromel
 * Suffix on literals need to be space (later gcc compiler makes it an error) - first wave of fixes
 *
 * Revision 1.9  2005/11/22 21:51:53  fisyak
 * Add NTuple for svt and ssd hit
 *
 * Revision 1.8  2004/01/13 21:06:04  fisyak
 * Add TpcHitNtuple usind IdTruth info
 *
 * Revision 1.7  2003/09/10 19:47:22  perev
 * ansi corrs
 *
 * Revision 1.6  2000/04/20 16:59:47  calderon
 * Pick up the makers with the new names
 * Change the name from "McAnalysis" to "StMcAnalysisMaker"
 * No longer use the helix, use the primary track momentum when available
 * (also avoids dependency on StEventSummary)
 * Denominator for mom. resolution histograms is now simulated momentum.
 *
 * Revision 1.5  1999/09/10 19:11:15  calderon
 * Write the Ntuple in StMcAnalysisMaker into a file.
 * This way it can be accessed after the macro finishes,
 * otherwise it gets deleted.
 *
 * Revision 1.4  1999/09/09 23:59:38  calderon
 * Made the following changes:
 *
 * -book histograms and ntuple in Init()
 * -do not delete the histograms, they are supposed to be
 *  deleted automatically by the chain
 * -don't create the canvas here, now done in the macro
 *
 * Revision 1.3  1999/07/29 15:08:33  calderon
 * Include Mom. Resolution example (Histograms & Ntuple)
 *
 * Revision 1.2  1999/07/28 20:27:30  calderon
 * Version with SL99f libraries
 *
 *
 * Examples to use the structures from
 * StMcEvent and StAssociationMaker
