Railsification of 1800 app

Added the Rails framework to the work we've done.  

It's only working for a 3 and 4 digit combination right now, but does use the number you search for.  Pulls it from the query string for now.

The controller (back end) is ugly right now and can be refactored.

Tests will need to be re-factored into Rails specs.

Front end has no validation, but I figured you'll need some time to figure out how you'll integrate the front end piece with Rails.

That it.  Boom.  Done.  Tacos.  :)
