Support for Cypher queries.  Test currently FAILS, but this is due at least in
part to a defective test that assumes auto indexing is enabled when in fact it
is not.
Add doc comment.
Use serviceRoot to populate Database struct fields, rather than being included
as a field itself.
Update references to db serviceRoot fields to now refer directly to Database struct fields.
Disable cypher query test until it is finished.
