missing documentation

[julou]

I copy/paste some email discussions for the records of what is still missing in the wiki:

• explain moma_preprocess requirements regarding input file names
• explain how to launch MoMA
• a version history page would really not be superfluous as well as a way to know which version (ideally which commit) is running
• upload sample datasets using LFS
• (distribute jars attached to releases rather than committed to the wiki). alternatively, hide the release tab on MoMA's homepage because it will be confusing (or delete the 2 existing releases)

• add gurobi in MoMA's requirements (and link to the free academic licenses page)
