WIP - Create list view of facts

This starts #28 - "As a user, I can see a list of all the facts"

A couple of things that need to be decided:

1. What is the actual navigation structure - how does this fit into the app?
2. What should clicking on a fact do? Expand in place? Take the user to the detail page?
You might want to clean up some of the commented out bilerplate stuff if you don't need it.
