Start fleshing out Groups API, with some tweaks to the model interfaces.
Improve fluency of the Query view list interface, and prepare for more advanced querying.
Add a (seemingly very inefficient) page function that returns info about the totals along with offset and limited items.
Add paging for agents.
Once again change format of setAccessor API, so it no longer takes graph ids.
Remove unused imports
Make it possible to specify on a @Fetch annotation the number of
traversals the @Fetched relations should include when serialized.
The vertex serializer also now has a mechanism to prevent runaway
recursion by including a maxTraversals member, which is decremented
every time a relationship is followed.
Rename and cleanup
Revert "Rename and cleanup", which includes a typo which breaks
everything.

This reverts commit c954774eab836e4086ebf3f8a73a138f9d5e3d88.
Rename and cleanup of comments
Skip importer tests while LOC site is down, because EAD DTD validation fails.
Remove exclude
Expose the base url
Add a test for Cypher.
Call test something more sensible
Remove needless cypher test.
Add missing @After annotation. I think at one point it was missing for a reason but due to SCM FAIL on my part this reason is obscure.
Fix use of wrong function when adding user to group: TODO: Audit log and unit tests.
Make group membership of other groups a @Fetched property
Add logging to the add/remove group action (which still needs fleshing out further.)
