-     *  RabbitMQ sends a message in multiple frames to its consumers.
-     *  The AMQP-CPP library collects these frames and merges them into a 
-     *  single AMQP::Message object that is passed to the callback that
-     *  you can set with the onReceived() or onMessage() methods (see above).
-     * 
-     *  However, you can also write your own algorithm to merge the frames.
-     *  In that case you can install callbacks to handle the frames. Every
-     *  message is sent in a number of frames:
-     * 
-     *      - a begin frame that marks the start of the message
-     *      - an optional header if the message was sent with an envelope
-     *      - zero or more data frames (usually 1, but more for large messages)
-     *      - an end frame to mark the end of the message.
-     *  
-     *  To install handlers for these frames, you can use the onBegin(), 
-     *  onHeaders(), onData() and onComplete() methods.
-     * 
-     *  If you just rely on the onReceived() or onMessage() callbacks, you
-     *  do not need any of the methods below this line.
