a little backbone refactor

Simple little repo demoing a refactor.

To get started, install lineman, clone the repo, then run npm install inside the repository root directory.

If you run

$ lineman run --force

You'll see at localhost:8000, a little example sign up page. It's implementation is in app/js/sign-up.js.

If you switch to the backbone branch (you'll need to restart lineman), the same toy app will have been refactored to basic backbone objects.
