Maybe if major changes are planned it might be good to make a tag, and a release. So I can peg calphy to that, and test and update as new changes come out.

I do not think these changes are major it is basically just about moving redundant internal code which we previously had in both pympipool and pylammpsmpi to just pympipool and have pylammpsmpi depend on pympipool. Still I agree once the two open pull requests are merged I am going to create a new release.
