 * Description: part of STAR HBT Framework: AliFemtoMaker 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.
 *
 ***************************************************************************
 *
 * $Log$
 * Revision 1.1.1.1  2007/03/07 10:14:49  mchojnacki
 * First version on CVS
 *
 * Revision 1.2  2005/06/28 23:12:24  chajecki
 * UncorrectedNumberOfNegativePrimaries() -> UncorrectedNumberOfPrimaries()
 *
 * For data taken in Y2 and later the centrality definition bases
 * on UncorrectedNumberOfPrimaries() while for Y1(AuAu@130)
 * it based on UncorrectedNumberOfNegativePrimaries().
 * But in many places of HBT code the number of negative primaries
 * was used as a multiplicity for all productions.
 * This has been fixed.
 *
 * Revision 1.1  2001/11/11 18:34:14  laue
 * AliFemtoPicoEventCollectionVectorHideAway: updated for 3d grid
 * AliFemtoVertexMultAnalysis: new
