   variable declaration information and generate the associated wrapper
   code later.  Yikes!

   This really only works in a limited sense.   Since we use the
   code attached to the nested class to generate both C/C++ code,
   it can't have any SWIG directives in it.  It also needs to be parsable
   by SWIG or this whole thing is going to puke.
