Format all Python files consistently

[jabagawee]

The files in this repository currently follow no formatting standards, which causes inconsistencies in things like using tabs or spaces for indentation. We use yapf to format every file in the repository with the following command:

yapf -i -r .

This normalizes all of the code in the repository to follow a single standard and also makes it easy for future contributors to ensure that they are following the formatting standards (they simply have to run yapf themselves before committing).

Sorry if this commit causes a lot of churn to the code, but it should be safe given that yapf is very battle-tested and has been used for countless other Python projects.

Fixed tabs in another commit. Taking a look at the other problems. Seems that the "line too long" errors refers to extremely long string constants, but stay tuned for more.

[jabagawee]

Note: this PR looks best when viewed in split mode.

[jabagawee]

Thanks for all your feedback, @johnhawkinson. I will take a look to see if there's a better way to handle all of the inconsistencies that you pointed out.

If we're going to play this game, may I suggest that we add an editorconfig file as well?
