Initial check in of scoring.xml documentation. I have also added lucene.css stylesheet and included it in the Anakia Site VSL, although I am open to other ways of including style information on a per document basis (I just don't know Velocity to make the changes).

I have not linked in scoring.xml to the main documentation yet, as I wanted others to proofread/edit before making it official.  Once it is official, I will hook it in via the projects.xml
