/**
 * This file provides one half of a test and example of a pub-sub
 * style of interaction. See topic_listener.cpp for the other half, in
 * which the logic for subscribers is defined.
 * 
 * This file contains the publisher logic. The publisher will send a
 * number of messages to the exchange with the appropriate routing key
 * for the logical 'topic'. Once it has done this it will then send a
 * request that each subscriber report back with the number of message
 * it has received and the time that elapsed between receiving the
 * first one and receiving the report request. Once the expected
 * number of reports are received, it sends out a request that each
 * subscriber shutdown.
