5 
6 \brief Generates the 'final state' hadronic system in v RES interactions.
7  It adds the remnant nucleus (if any), the pre-selected resonance
8  and the resonance decay products at the GHEP record.
9  Unlike the SPP thread, in the RES thread the resonance is specified
10  at the time an interaction is selected but its decay products not
11  (semi-inclusive resonance reactions). The off the mass-shell baryon
12  resonance is decayed using a phase space generator. All kinematically
13  available decay channels are being used (not just 1 pi channels).
14  Is a concrete implementation of the EventRecordVisitorI interface.
