Epic #2: Receiving/Decoding NMEA messages + Creating/Updating/Publishing AIS Messages and AIS Tracks
Publish messages to AISTrack_TOPIC for each time a AISTrack is updated containing the updated AISTrack and a list with its AISTrack messages
Description
When receiving an AIS Message for a given AISTrack, two situations can occur:
A new one will be created if the AISTrack has not existed.
If the AISTrack already were in the system, for each AISTrack message received, the respective AIS Track attributes contained in that message will be updated. (The message type attribute will represent, therefore, the type of the last AIS message received for that AISTrack)
When an AISTrack is created (or receives an update), a message will be published to AISMESSAGE_TOPIC containing a pair of :
The updated AISTrack representing the current composition (data-merged) from the different AIS Messages received for that AISTrack so far.
A list of all AISTrackMessages received for that AISTrack.
