/* Traits for enums. This is bit of a sneaky trick needed because a generic template specialization of enums
   is not possible (unless using template meta-programming which SWIG doesn't support because of the explicit
   instantiations required using %template). The STL containers define the 'front' method and the typemap
   below is used whenever the front method is wrapped returning an enum. This typemap simply picks up the
   standard enum typemap, but additionally drags in a fragment containing the traits_asval and traits_from
   required in the generated code for enums. */
