Docs architecture: Refined (suggestions requested)

[Cheetham, Anastasia]

I've made some expansions and refinements to the documentation architecture found at
    http://wiki.fluidproject.org/display/fluid/Documentation+Architecture

In particular, I've tried to apply an order to some of the sub-topics, as they might appear in textbook-style documentation. I'd really appreciate some suggestions for improvements to this ordering, in particular for the Concepts and Framework sections. For the How-to sections, I think the order is a bit less important (but I'm open to being convinced otherwise).
