\class    genie::LwlynSmithFF
 
\brief    Abstract Base Class:
          implements the QELFormFactorsModelI interface but can not be
          instantiated.
 
          Its sole purpose of existence is to transmit common implementation
          (related to the Llewellyn-Smith model for QEL vN scattering) to its
          concrete subclasses: LwlynSmithFFCC, LwlynSmithFFNC.
