\class    genie::RSPPResonanceSelector
 
\brief    Generates an intermediate baryon resonance for exclusive interactions
          proceeding through resonance productions and adds it to the event
          record. The resonance is selected based on its contribution to the
          selected exclusive reaction cross section.
          Is a concrete implementation of the EventRecordVisitorI interface.
