Added the rspec gem and the capybara gem. We updated the gemfile, used
the generators for rspec unit tests for our student model, then updated
the spec_helper and test environment file for the capybara integration
test in the spec/features directory. The issue I saw in class was that
the integration test needed to have _spec.rb at the end of the file
name.
rake spec
runs all the rspec tests in the spec directory - they have to have _spec
in the filename to be run.
