Release template purposal

[jtroussard]

Considering the many moving parts of the release process and integration with the PyPi, it would be beneficial to create some sort of release protection or employ a template. I have not researched this specifically but wanted to open the conversation here on this issue to explore the possibilities.

Some specific things to consider could be creating a check list or template guiding team members to:

1. update README.md if necessary
2. update setup.py
3. does the documentation need to be recompiled
4. determine version update

I imagine there are other points to cover.

Feedback highly encourage, positive/critical any and all welcome.

This is a great place to document, we can flesh this deployment/releases section out for now and see how that serves the community/maintainers.
