* Perhaps one team can also go over some key classes and improve their
code documentation, especially in the core / kernel / base / atom modules.
I suggest a beautiful method to do this. Use WARN_IF_UNDOCUMENTED from
doxygen, and a simple rule: Warning, then failed commit. I would find it
quite more useful that common existing rules that are just sugar: 80
characters line, python indentation, blah, blah.
