+ * @brief		This class manages sending and receiving of

+ * @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.
+ *
+ * Please keep in mind that FreeRTOS offers different calls for message queue
+ * operations if called from an ISR.
+ * For now, the system context needs to be switched manually.
