 * intended for use by classes that act as delegates to a given widget.
 *
 * @param {Object} object       the instance to check for the protocol conformance
 * @param {Array} protocol      the interface for which to check the conformance
 * @return {Boolean} true if the given object conforms to the specified protocol; otherwise, returns false
