I don't know the code in question, but answering in broad terms: Not much,
really, since it doesn't buy you anything special. It is mainly a way to
organize the code and bundle up classes that the author thought should be
bundled together. Python is not Java, where classes within classes *really*
are important. I remember reading recently a thread at python-dev where
Guido van Rossum asked for a real use-case for inner classes. After a while
W. Dorwald seemed to have found one since it got a "really cool!" from the
BDFL.
