Make it a directive

[mr-mig]

Why not make it a directive so that stylesheet injection become declarative and not imperative in the controller?
Something like:

<ng-style src='css_from_current_module.css'><ng-style>

It's an interesting idea. You want to write the CSS dependencies directly in the view. My approach was to managing it with the route.

If someone pull a request I will accept it.
