Thanks for the report.

I am ashamed with the comment part. Usually, I am adding more comments than code in my codes. However, this time, I took over the code from someone else and just stick to the state it was at retrieval. I will improve it for the next commit, but most probably file by file (because it is really too much work in one shot, and I don't master yet all the details of the code). Anyways, thanks for pointing this out!

Concerning the PR comment, I decided not to do it as the only developer working on the code at the moment. But this is a bad practice. Again, it is a bit too late for v0.3 but I will move to the more traditional github workflow for v0.4, which may be a good incentive to other dev to join in. For the v0.2 to v0.3 transition, I will instead detail more which commit does what.
