     * A 'handle' used to represent an AMQP queue in the Channel
     * methods. Creating an instance of this class does not cause the
     * queue to be created on the broker. Rather, an instance of this
     * class should be passed to Channel::declareQueue() to ensure
     * that the queue exists or is created.
     * 
     * Queues hold messages and allow clients to consume
     * (see Channel::consume()) or get (see Channel::get()) those messags. A
     * queue receives messages by being bound to one or more Exchange;
     * messages published to that exchange may then be routed to the
     * queue based on the details of the binding and the type of the
     * exchange (see Channel::bind()).
     * 
     * Queues are identified by a name. They can be exclusive (in which
     * case they can only be used in the context of the connection
     * over which they were declared, and are deleted when then
     * connection closes), or they can be shared. Shared queues can be
     * auto deleted when they have no consumers.
     * 
     * We use the term 'temporary queue' to refer to an exclusive
     * queue.
