Add tooling section #7

Closes #7 

- Added section addressing tooling
- Replaced dumb quotes with smart quotes where appropriate (see http://smartquotesforsmartpeople.com/)

Review please @harrison @jackfranklin . In particular, is the ui-router example correct?
I know this wasn't a change in this PR, but I find this sentence a little clunky. How about:

"The page is rendered only when all data is available. This means views are only rendered once all the required data is available, and you avoid the user seeing any empty views whilst the data is loading"
