*
* \defgroup mqtt-engine An implementation of MQTT v3.1
* @{
*
* This application is an engine for MQTT v3.1. It supports QoS Levels 0 and 1.
*
* MQTT is a Client Server publish/subscribe messaging transport protocol.
* It is light weight, open, simple, and designed so as to be easy to implement.
* These characteristics make it ideal for use in many situations, including
* constrained environments such as for communication in Machine to Machine
* (M2M) and Internet of Things (IoT) contexts where a small code footprint is
* required and/or network bandwidth is at a premium.
*
* The protocol runs over TCP/IP, more specifically tcp_socket.
* Its features include:
*
* - Use of the publish/subscribe message pattern which provides
* one-to-many message distribution and decoupling of applications.
* - A messaging transport that is agnostic to the content of the payload.
* Three qualities of service for message delivery:
* -- "At most once" (0), where messages are delivered according to the best
* efforts of the operating environment. Message loss can occur.
* This level could be used, for example, with ambient sensor data where it
* does not matter if an individual reading is lost as the next one will be
* published soon after.
* --"At least once" (1), where messages are assured to arrive but duplicates
* can occur.
* -- "Exactly once" (2), where message are assured to arrive exactly once.
* This level could be used, for example, with billing systems where duplicate
* or lost messages could lead to incorrect charges being applied. This QoS
* level is currently not supported in this implementation.
*
* - A small transport overhead and protocol exchanges minimized to reduce
* network traffic.
* - A mechanism, Last Will, to notify interested parties when an abnormal
* disconnection occurs.
*
* The protocol specification and other useful information can be found
* here: http://mqtt.org
