ServiceMatrix Documentation Restructuring

Documentation restructuring is complete. Still need to write one topic on how to change the transport, but otherwise, everything is ready for review. Because there are a lot of changes, I've setup a preview site here:

http://particulardprothero.cloudapp.net/servicematrix/

That site pulls from the servicematrix-restructure branch of docs.particular.net.

This PR is in support of Issue #482, @indualagarsamy @gbiellem @dannycohen
