/**
 * @file PhysListLoader_module.cc
 *
 * @brief A dummy module that forces library loading to register a
 * physics list.
 *
 * @author Marco Del Tutto (mdeltutt@fnal.gov)
 *
 * This module is a dummy module that does not act in any way
 * on art::Events. This module, and in particular the library this
 * module is built in, is linked to the PhysicsLists library in
 * this same directory. Running this module causes the PhysicsLists
 * library to be loaded, and so the Physics Lists to be registered
 * to the Geant4 PhysListRegistry
 *
