Auto pep8 the code

[beckermr]

I hate myself for saying this, but a lot people expect pep8 looking code. Biggles is def not very pep8 ish. I am ok with 120 character lines.

I think the biggest issue I have is the opaqueness. The code is highly general, which is good if you already know how it works, but since I don't a lot of it seems like magic. Maybe as part of the style effort we could make some of the data structures more transparent.

Looks like your message was cutoff. I agree. The objects are quite opaque. Docs would help, but the layered inheritance structure hides methods.

This issue is related to #19. I will make a separate issue for cleaning up the object structure.
