going through this tutorial to get the basics down and get angularjs up
and running
- Added tasks routes for Index and Show
- debugged routes, the guide as using an old way of declaring scopes
which no longer seems to work
- json requests respond appropriately
- the angular isn't receiving or processing the json correctly. This is
what I need to do next.
- deleted public index / favicon
