0029 // Description: Singleton class to evaluate multi-body momentum distribution
0030 //      functions based on initial state codes and multiplicity.
0031 //
0032 // NOTE:  Separate multiplicity-3 generators are not used, per V.Uzhinsky
0033 //
0034 // 20130619  Change singleton instance to be thread-local, to avoid collisions.
0035 // 20130620  Address Coverity warnings about missing copy actions
