GraphQL, UI Updates and More

With v0.0.3, we integrated GraphQL driven by Apollo (https://github.com/apollostack). In doing so, we radically simplified the front end and back end.

• Created the /graph folder, which runs our graph endpoints
• Radically refactored many packages in /client
• Refactored service code into the /services folder, simplifying the /models
• Many new features and bugfixes
