///\brief Vertex generator for neutrino-proton elastic scattering.
///
/// \details
/// This class generates a vertex of a neutrino-electron elastic scattering.
/// It is strongly based in an initial implementation by Christopher Jones and adapted from the neutrino-electron elastic scattering vertex
/// generator.
///
/// REVISION HISTORY:
/// - 30/04/2013 C. Jones (Oxford):
///	    -# Original implementation
/// - 26/11/2014 Matt Strait: Doxygen fixes
