/**
* topic_publisher.cpp:
*
* This program is one of three programs designed to be used
* together. These programs implement a publish-subscribe example
* using the "amq.topic" exchange. In the example multiple listeners
* can subscribe to the same queues for TTL messages.
* The TTL messages are all ticker price data. Messages are
* browsed and therefore shared among the multiple listeners.
* Messages timeout using TTL so that they don't stay in the queue
* for too long and fill it up.
* Local exclusive LVQ are also declared for market data.
*
* declare_queues.cpp
*
* Declares several non-exclusive queues bound to the amq:topic exchange
*
* topic_publisher.cpp
*
* Sends messages to the "amq.topic" exchange, using the
* multipart routing keys for ticker price and market data
* Ticker messages are sent using a TTL value.
*
* topic_listener.cpp (this program)
*
* Subscribes to non-exclusive queues in NOT_ACQUIRE mode for
* ticker price data and declares two LVQs for market data.
*
* Multiple listeners can be run at the same time.
