Overhaul the docs

This is a major redesign and overhaul of the docs and can be previewed at [http://ascott1.github.io/capital-framework/](http://ascott1.github.io/capital-framework/). This is by no means finished, but I think it's in a state that we can make it "official."

We're ditching "The" right?
