Basic grid setup

I did a lot of work on the layout this weekend. I wrestled with Susy (our grid system) and the shortcodes created by Aesop Story Engine to eventually get a functional model for going forward.

It's all pretty raw right now, though. This indicates the general direction we'll be heading in, and eventually how we'll work with content, but it needs work.

I only tested thoroughly with ASE's Image Component, as it's the simplest of all the components. That said, it does work to some extent with some of the other components. I plan on doing some further testing with the other components.

There is very minimal documentation as of now. I plan on expanding this a great deal, as it will be especially helpful to @pmcc8 when we get closer to loading the real content on a staging server somewhere. @pmcc8 stay tuned. I'll let you know when we get closer to that point.

Rob, do note that it will be very helpful for you to grab a copy of my database at this point because I've created a few posts for component unit testing.
