Created a new documentation branch.

Began to create a structure within which to write the actual documentation.
Changed the length of the titles, as they were displaying really weirdly on Github.
Wrote the basic page for the introduction.

Made sure to include a link to the AMITA13 paper, and a caveat about the built in security of the system.
Wrote an initial installation document.

I haven't actually followed these instructions on a fresh install to check that they work, but this is something that can be done once the installation process is a little more streamlined.
Fixed some typos in this file.
Added a link back to the docs index at the bottom of the page.
Rewrote the BASE README.md to reflect the fact that the documentation is actually starting to exist.
Added the node-controller documentation.
