\brief    nu/nubar + e- scattering differential cross section \n
          The cross section algorithm handles:
             - nue/nuebar + e- -> nue/nuebar + e- [CC + NC + interference]
             - numu/nutau + e- -> numu/nutau + e- [NC]
             - numubar/nutaubar + e- -> numubar/nutaubar + e- [NC]
             - numu/nutau + e- -> l- + nu_e [CC]
 
          Is a concrete implementation of the XSecAlgorithmI interface. \n
