\class    genie::GLRESKinematicsGenerator

\brief    Generates values for the kinematic variables describing Glashow resonance.
          Is a concrete implementation of the EventRecordVisitorI interface.
          Part of its implementation, related with the caching and retrieval of
          previously computed values, is inherited from the KineGeneratorWithCache
          abstract class.
