\brief    The INTRANUKE intranuclear hadron transport MC.
          Is a concrete implementation of the EventRecordVisitorI interface.

\ref      R.Merenyi et al., Phys.Rev.D45 (1992)
          R.D.Ransome, Nucl.Phys.B 139 (2005)

          Current INTRANUKE development is led by S.Dytman and H.Gallagher.
          The original INTRANUKE cascade MC was developed (in fortran) for the
          NeuGEN MC by R.Edgecock, G.F.Pearce, W.A.Mann, R.Merenyi and others.
