I believe that is the latest code.  The student working on the project
in 2012 dropped out (it turned out he was trying to do an internship as
well as GSoC, which really isn't a good idea) so things may not be in a
very polished state.

Your other questions all sound like good ones, but I don't really know
the answers.  Parth implemented the original letor code in 2011, and was
the mentoring the 2012 project most actively, plus he's more up on the
theoretical side, so hopefully he can answer these questions.

Cheers,
