\class    genie::SPPXSec

\brief    Computes the cross section for an neutrino resonance SPP reaction.

          Before computing any SPP cross section this algorithm 
          computes and caches splines for neutrino resonance SPP  cross 
          sections. This improves the speed of the GENIE spline construction 
          phase if splines for multiple nuclear targets are to be computed
          (for case without Pauli-blocking).

          Is a concrete implementation of the XSecAlgorithmI interface.\n
