Making a release to PyPI

We should really automate some of this.

1. Get the latest code:

$ git checkout master
$ git pull

2. Get the tag of the last release

$ git describe --abbrev=0 --tags

3. Inspect the changes since then and update the Changelog

$ git log 3.2.9... $ vi Changelog

Change log format like so

Version <VERSION_NUMBER> 2018-10-04                                                  
 * Add check for wiping db on test run - Athanasios
 * Correct function name in doc string - Henry Jordan

4. Update the version number in setup.py

$ vi setup.py

5. Commit the changes, tag and push

$ git commit -a -m "<VERSION_NUMBER> release"
$ git tag <VERSION_NUMBER>
$ git push --tags

6. Make sure you have twine and are auth'd with PyPi

$ pip install twine

7. Create and upload the dists

$ rm -rf dist/*
$ python setup.py sdist
$ twine upload dist/*

8. Update read the docs with the latest
