Pythonification of the source

Fixing various non-Pythonic things about the source inc.

- variable and function names are now lowercase
- logging.info and logging.warn used for output and warnings
- += 1 on accumulators
- remove redundant ( ) on a lot of if statements

This does not alter the function, just hopes to make it more easily
maintainable.
