Installation requires Qt 4.7. The Internets will tell you how to get that for your particular environment. Installation requires Qt 4.7. [`capybara-webkit`](https://github.com/thoughtbot/capybara-webkit) has the best instructions for installing Qt on various
operating systems, so I'm not going to duplicate their work.

`console.log()` also works. If Jasmine is loaded, you get to use `jasmine.pp`, Jasmine's built-in pretty-printer. `console.log()` also works. It uses `JSON.stringify()` to serialize objects.
