\class    genie::HadronTransporter

\brief    Intranuclear hadronic transport module. 
          It is being used to transfer all hadrons outside the nucleus without
          rescattering -if rescattering is switched off- or to call one of the 
          supported hadron transport MCs -if rescattering is switched on-
