Getting Started: Changing router in 'displaying model data' raises errors

So forgive me in advance, I’m obviously totally new to ember (and pretty new to JS in general as well. I’m going through the enhanced Getting Started tutorial, following it line by line, (unless I missed something) when my browser decides to render nothing but the background. I backtracked and noticed it happens immediately after altering the router as directed here:

I commited and pushed to github here:

^The first commit rendered in the browser fine, the second commit is broken, if you want to see the difference.

This is my console output:

any ideas are greatly appreciated.

the problem is in first line

Uncaught ReferenceError: Todos is not defined todo.js:1

todo.js is called before application.js and router.js.
