[infinispan-dev] Some docs on OGM

[Emmanuel Bernard]

After being gently reminded by Manik several times, I've finally sat down and wrote a page on Hibernate OGM.
http://community.jboss.org/wiki/HibernateOGMGeneralInformations

It contains several sections:
 - how to use
 - how to contribute
 - what is supported
 - architecture

The wiki went wild, so if you edit it, copy it first (I know the text is blank on blank, go figure) in your favorite text-only editor and then paste back in a Wiki Markup element.
