+ * @brief GQUEUE header file.
+ *
+ * @addtogroup GQUEUE
+ * @brief GQUEUE provides queue management. There are 3 types of queues:
+ * <ul><li><b>Asynchronous Queues (ASync) </b> - Queue operations never block</li>
+ * <li><b>Get Synchronous Queues (GSync) </b> - Queue Get operations block until something is placed in the Queue</li>
+ * <li><b>Put Synchronous Queues (PSync)</b> - Queue Put operations block until the element is removed from the Queue</li>
+ * <li><b>Fully Synchronous Queues (FSync)</b> - Queue GET and Put operations block</li>
+ * </ul>
+ * We need 4 types of queues even though fully synchronous queues support all operations including asynchronous
+ * operations because fully synchronous queues have the highest storage requirements. The other queue types are
+ * optimizations. Efficiency IS important to use (particularly RAM efficiency).
+ * In practice we only implement ASync, GSync and FSync queues as PSync queues are of dubious value.
