Overview

A query object based on agents, credentials, and resources.

This query mirrors the essence of the Checkpoint semantics; that is, it finds grants for any supplied agents, for any supplied credentials, for any supplied resources.

It can take single items or arrays and converts them all to their tokens for query purposes.
