Overview

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

This is a helper to capture a set of agents, credentials, and resources, and manage assembly of placeholder variables and binding expressions in the way Sequel expects them. It can take single items or arrays and converts them all to their tokens for query purposes.
