add routes to our routing table by modifying config/routes.rb
removed the public/index.html file so that our root route is used instead. Anything in public that will handle the request will skip the app (and our routing table).
added a welcome controller and hello action/view to handel our example custom route. This is also where our root route directs to. We are using the named scopes from the Student model in this controller. This was generated using
rails g controller Welcome
