Separate build and test utilities to better define what each should do
Fix build tool not stopping on build error, better to halt and make
error very apparent
Import Neo4j embedded database and create simple static class for
interfacing
Stub sample unit test for GraphDatabase
Added Stub for user and code for Citation and Session.
Modified API, added Identity interface (temperary)
-addEmail should require user to verify email with a ClaimToken just as register would; there's no reason to assume the user owns other email's.

-Updated phrasing to be consisted with proposed model:
  *TrustNodes are an individuals entry point into the trust network, Email's and Users are just associated with them.

-Fixed typos in data classes and added last night's work on identity
(Will be largely restructured soon according to http://i.imgur.com/5jQl471.jpg, but wanted things to be compiling correctly in the mean time)
