Billing: rails app for test task with backbone.js

There is a basic rails & backbone.js scaffold. I haven't gone in too much details, just followed the specification. It took me about two hours total to set up this app. Transactions' `index`, `show` and `destroy` actions are driven by backbone, `new` and `edit` are just rails pages, because there is a form and it would take too much time to integrate form builder or something into clean backbone.js

:warning: please seed test database too. I didn't create fixtures/factories

Thanks
