[Tutor] An example extension class

[Daniel Yoo]

Hello everyone!  I was playing around with the Python/C API, and thought
it would be fun to write a C extension.  I've written a pybitmap module
written in C, so it might help people who're trying to learn how to extend
Python.  Here's the link:

I'd be greatful for any comments about the code --- I know that it can use
a lot of improvement.  Thanks again!
