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?
this is a little unclear I think - better to talk about how Lodash is a "utility belt" full of useful functions that we use throughout our code base.
