\class    genie::rew::GReWeightNuXSecNC

\brief    Tweak NC level in a gross way (scale by a given factor).
          More detailed rew. functions also exist for specific NC sources.
          RES NC cross section rew. is also handled by GReWeightNuXSecNCRES.
          DIS NC cross section rew. is also handled by GReWeightNuXSecDIS.
