Tweaking the language to try to be more consistent (our ubiquitous language)
Refactoring the first few chapters to create a resource first, then show GET

This was a recommendation from William - the idea was to immediately show the Location header
on the POST, instead of showing a GET, then a POST, then add the location header. I like the
simplicity of it - POST, then GET
Taking into account the rest of William's notes:

1) Rearranging things, putting PUT/DELETE above Hypermedia
2) Removing many todos/questions, replacing with answers
