Issue #169

2. Overview of Solution

This PR addresses two tickets, see above.

I added in the pre-push documentation and also am offering up a solution to demonstrating outputs without compromising the ability to easily copy code from the README.md on Github. I am open to feedback on the implementation.

This also solves an issue I was experiencing with Github Desktop when running pre-push before pushing up to Github. The solution was to make sure the tests were running in pipenv shell. @jimbandrews assisted with this solution

Other changes:
Cleans up lingering linting issues

3. Tools Used

pipenv run

4. Testing Strategy

Tried to run this with Github Desktop and from shell in terminal. Both successfully ran the tests.

5. Future Implications

6. Screenshots

@GitLukeW During the process of debugging, I uninstalled and reinstalled celery. When I did this, I also ran pipenv install and it looks like it updated boto3 as well. Do you think this is going to cause an issue? If so I can work on reverting it.

Tested out locally, and it works. Good catch!
