Description of Changes

Idea for avoiding confusion with our install requirements, happy to take suggestions for other ways to do this though.

fixes #926

We may want to create a requirements folder and have a few requirements.txt files inside of them: requirements-dev.txt and requirements-docs.txt.

We could do that but is it worth it for only 10 packages? Happy to change to that though if you prefer.

Updated and replaced with #978.
