> Goal:  Place a network of Routers between a client and a broker such that the transfer
of messages between the client and broker occurs normally and no code changes are needed in
the client or broker.
> This feature enhances Dispatch Router such that the transfer of a message with an address
is divided into multiple "legs" with "waypoints" in between.  For example, a message may be
produced, routed to a broker queue (the waypoint), then later dequeued from the queue and
routed to a consumer.  In this example, the address is always the same (i.e. the name of the
queue), but the routing is divided into two distinct paths, each with its own distinct semantics.
> This feature generalizes the notion of leg (called phase) and waypoint so multi-phase
paths can be configured.  There is not reason that a waypoint need be limited to a broker
or queue.  It is simply a pass-through endpoint that takes ownership of a message for the
time it holds the message.
