This did get out, but I can't answer except to suggest looking at code for 
other C extension modules.  Nested (inner) classes are fairly rare, but I 
presume that once you know how to add attributes in general, you add class 
as an attribute in the same way you would add an int, etc, as an attribute. 
(And if I am wrong, you should certainly get another response '-).
