Run through this to hope to get css to show on rails4 app in heroku:
http://stackoverflow.com/questions/16271696/cant-get-css-working-on-heroku-using-rails-4-with-bootstrap-saas-gem
introduce have_selector to rspec to test for specific HTML tags
refactor tests to use shared_examples.. and add let to each page test
Add spec helper to test full_title method.
Add test for links.
Modify test to have_content instead of have_title(full_title('xyz')), tests
did not pass with the later case since the pages did not have titles..?
