 *     error,
 *     resourceState,

 *
 * * loading - will be true as long as the result is still being fetched from
 *             the server.
 * * error - Will be null or an error object.
 * * resourceState - A state object. The `.data` property of this object will
 *                   contain the parsed JSON from the server.
