\class    genie::LwlynSmithFFDeltaS.h

\brief    Is a concrete implementation of the QELFormFactorsModelI:
          Form Factors for Quasi Elastic CC vN Delta S=1 scattering.

\ref      Equations for the strange form factors are taken from Cabibbo
          and Chilton, Phys.Rev. 137 (1965) B1628-B1634 and
          Alam et al., J.Phys. G42 (2015) no.5, 055107.
