add ring

added ring and made a quick home route. I like this implimentation
better than my original implementation. I figured out how to serve
static HTML from whatever route I want. I'm starting to really like
ring.
basic routes and controllers

added basic uri handling for the start of the application. It takes a
uri, parses it, and determines which controller to pass it to, if the
route doesn't exist, it serves a 404 page error
