Merge pull request #4 from JonathanTR/development

Add testing frameworks to application
Merge branch 'master' into development.

* I made a quickfix on github to fix the wording in the should statement of a test. After I pulled those changes down to local master, the development branch was behind on this change.
Quickfix: change gem 'capybara-rspec' to gem 'capybara'

* Capybara was previously invoked under the wrong gem name.
