\class    genie::RSPPHadronicSystemGenerator

\brief    Generates the 'final state' hadronic system in v SPP interactions.
          It adds the remnant nucleus (if any) and the baryon resonance decay
          products at the GHEP record. The resonance decay products are pre-
          determined since in this thread we generate exclusive SPP reactions.
          The module uses a simple phase space decay.
          Is a concrete implementation of the EventRecordVisitorI interface.
