Proof read new university documentation

[zoe-1]

Have updated the university, see PR #200 for details about the update. Would really appreciate some people to look over the new documentations relating to the university and give feedback / proof read it. The documents most needing attention are:

• README.md
• ./guides/contents.md
• ./guides/getstarted.md
• ./guides/groupDevelopment.md
• ./assignments/* The links in the contents should all link to the assignments.

Ideally, just start at the README and follow the flow of documentations logic and give feedback where things are unclear etc.

Don't be bashful if you are new to hapi. Perhaps your perspective is most needed.
