Black formatting

[hazmat345]

This PR runs back on the following:

• yapconf directory
• ~tests directory~
• setup.py

Edited to remove the tests directory. Running black with a line length to make the flake8 check pass significantly altered the tests package.

I'll need to add this to the .travis.yml before I accept.

@loganasherjones I added a black --check to the tox configuration. I set flake8's max line length to 88 to match what black is creating, if that's not what you want just let me know.
