Added a Gem to our application. To add the twitter-bootstrap-rails gem
I:
added it to the Gemfile (I also added less-rails and therubyracer)
ran bundle install
rails g bootstrap:install Less (on Windows you have to use static and
not add less-rails or therubyracer)
rails g bootstrap:layout bootstrap fluid
changed the students controller to use the bootstrap layout
