History file

We have added all your work from the previous chapters into the empty cookiecutter package you just created.

Since you last made a release of the package, you have written some pytest tests, fixed a bug, changed the supported versions of Python, re-styled some of the code using flake8, and added a few new additional files.

Now it is time for a new minor version release, so you need to update your package's HISTORY.md file.
