Where should we put poppy software files?

So I had a discussion with @omangin and I’m more and more convince what we should split the code.
We could use submodule to do that but it seems that git submodule are complicated to use for non-git-expert. I think we could try just to separate the repository and specify in the documentation that people have to keep up-to-date their pypot version.

If you are agree with that, do you have any suggestions about the name for this repository ?
For the moment, I randomly chose poppy-software as there is already a pypot-hardware repo for the mechanics and future electronics made by @Fdepraetre.
