/**
* @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.
