Adding R-Hardons to AthGeneration
In order to generate R-hadrons, there are some python helper functions that are needed and are coded up in the RHadrons G4Extensions package. This package has protection in the CMakeLists file against trying to compile anything more complicated when working in AthGeneration (as far as I can see this should still function correctly), so we should just get the python files installed in AthGeneration and be able to do the event generation.
