* @brief This class manages sending and receiving of
* message queue messages.
* @details
* Message queues are used to pass asynchronous messages between processes.
* They work like post boxes, where all incoming messages are stored in FIFO
* order. This class creates a new receiving queue and provides methods to fetch
* received messages. Being a child of MessageQueueSender, this class also provides
* methods to send a message to a user-defined or a default destination. In addition
* it also provides a reply method to answer to the queue it received its last message
* from.
* The MessageQueue should be used as "post box" for a single owning object. So all
* message queue communication is "n-to-one".
* For creating the queue, as well as sending and receiving messages, the class makes
* use of the operating system calls provided.

* @brief This helper object is used to forward verification messages
* which are generated by the Flight Software Framework.
* @details
* The messages can be relayed to an arbitrary object, for example a dedicated
* Verification Reporter. The destination is set by setting the static framework
* Id VerificationReporter::messageReceiver. The default verification reporter
* will be the PUS service 1, which sends verification messages according
* to the PUS standard.
