/**
 * Marker interface for notifications that are intended
 * to be used in point-to-point fashion i.e. there is at
 * most ONE subscribing class.
 *
 * There may be multiple broadcasters. We also permit
 * multiple instances of the subscriber class.
 *
 * The purpose of having this interface is to allow
 * the creator of a notification to declare that it
 * is being used for control flow and thus future
 * users should not add a subscriber because doing so
 * would risk interference and race conditions.
