/**
 * @file
 *
 * A waypoint sends/receives messages to/from an external entity such as a
 * broker as part of a multi-phase address.
 *
 * An address can have multiple phases. Each phase acts like a separate address,
 * but sharing the same address string.
 *
 * Phases are not visible to normal senders/receivers, they are set by
 * waypoints. Messages from normal senders go to the phase=0 address.  Normal
 * subscribers subscribe to the highest phase defined for the address.
 *
 * A waypoint takes messages for its in-phase and sends them to the external
 * entity. Messages received from the external entity are given the waypoint's
 * out-phase. Waypoints can be "chained" with the out-phase of one equal to the
 * in-phase for the next. Thus waypoints provide a way to route messages via
 * multiple external entities between a sender and a subscriber using the same
 * address.
