Release schedule / plan

[andreww]

We should discuss the best way to release the code for when you submit the pyDis paper. I would aim to host a copy of the code on pypi and to put the documentation on readthedocs, while keeping track on versions etc. here on github. I think this means:

1. Add a "tag" when you submit the code. Use this to generate a clean tarball for submission alongside the paper.
2. After any revisions and on acceptance create a new tag (for version 1.0.0?). This could point to the same version, or a later version. Use this to generate a new tarball for the comp phys letters repo.
3. In the meantime work out how to host a version of the code on pypi. This will mean that installation instructions can be "type pip install URL" and pydis will be installed.
4. Look at how to host the documentation on readthedocs and / or github pages.
