Got a demo working

Hey,

Take a look at this. It's a basic demo of it working. Make sure to run `rake db:migrate` on it. It will create a `users` table. There's a job that I added that creates a new user every 5 seconds.

If you checkout `http://localhost:3030/sample`, you'll see a widget that shows the user count, and one that shows the latest 5 users. Hope that helps.
