Integrate the docs from the Angular team

https://github.com/Urigo/meteor-angular-socially/blob/master/EDIT_THIS_TUTORIAL.md

@dotansimha @Urigo can we get this into the docs here: http://meteor-tutorial-tools.readthedocs.org/en/latest/

More and more people are going to use this, and it would be great to have the docs in one place.

I can give you commit access, if you want.

Start with EDIT_THIS_TUTORIAL.md in the linked meteor-angular-socially repository and compare it with the documentation at meteor-tutorial-tools.readthedocs.org/en/latest/. Determine how the Angular team material should be represented in the existing docs, then verify that the integrated content is available in the documentation site.
