Testing

Just setting up some basic testing components for us to discuss. 
I don't expect that you would always do all of these items, I just wanted to show that they are possible, and we can discuss their value. (though there are a few more examples I wanted to set up, but I'll add those in later)

You don't have to merge this into master right away, we can talk about it first
after you run bundle install, you should be able to fire off the tests with just the command:
rspec 
to run a single test file
rspec spec/controllers/contacts_controller_spec.rb
