Defining Python class methods in C

[Bryan]

i found one of my problems:

i was using METH_NOARGS for get_path.  when i changed to METH_VARARGS
my callback got called.  but the self variable in context_get_path is
NULL. so i can't get to the variables i stored in the context_object
from the __init__ call.
