Subject: Create 'pre-commit', add Python tests

* Create our 'pre-commit' hook script that runs flake8 on Python files in
  the staging area.
* Update test setup to create a git repository for testing.
* Add a test for the Python linter to confirm that it produces the
  correct output when trying to commit and that it only checks files in
  the staging index.
