Description

The API should expose the information about the authenticated user principal via AnzoClient. Most importantly, access to the user's URI should be exposed so that applications can use that to store user-specific preferences.

Adding a method to AnzoClient like:

AnzoPrincipal getUserPrincipal();

As a further step, we could consider actually exposing a method like:

ClientGraph getUserGraph();

which is a quick way to get a graph based on the user's URI with limited access control so tat only the user can read/write to it.
