Add a new constructor to Query
Query(String niql, Database db)
... that implements niql queries.
In addition, buried in this document:
API Spec (See section 4): https://docs.google.com/document/d/1FBN316lV0RXRibd71GKLGkgDZWSfKWhT-_2GZIKAoQY
... are many more changes that may have to be implemented. The first task will be, simply, figuring out what changes have to be made. Apparently included are:
1. FTS Match Functions (already implemented)
2. isValued and isNotValued operator (???)
