Stuart Buchanan f32a376a3e FG1000: EIS Fuel totalizer function 
FG1000 requires fuel quantity to be entered manually and uses a flow
computer to calculate the amount used.  Strange but true!

# Title : EMESARY flightgear standardised notifications
#
# File Type : Implementation File
#
# Description : Messages that are applicable across all models and do not specifically relate to a single sysmte
# : - mostly needed when using the mutiplayer bridge

#
# Ideally for notifications bridged over MP the message ID should be system unique.
# with that in mind 0-16 are reserved for model use; and may well be marked as not bridgeable
# however the most important thing is that as these notifications ID's are used the
# wiki page http://wiki.flightgear.org/Emesary_Notifications
var PropertySyncNotificationBase_Id = 16;
var AircraftControlNotification_Id = 17;
var GeoEventNotification_Id = 18;
# event ID 19 reserved for armaments and stores (model defined).
var PFDEventNotification_Id = 20;
#
# PropertySyncNotificationBase is a wrapper class for allow properties to be synchronized between
# modules. This can replace (or augment) the properties that are normally transmitted by multiplayer
# It is reasonably efficient with the MP2017.2
#
# Usage example - this can all go into one Nasal module somewhere.
#-----------
# var PropertySyncNotification =
# {
# new: func(_ident="none", _name="", _kind=0, _secondary_kind=0)
# {
# var new_class = PropertySyncNotificationBase.new(_ident, _name, _kind, _secondary_kind);
#
# new_class.addIntProperty("consumables/fuel/total-fuel-lbs", 1);
# new_class.addIntProperty("controls/fuel/dump-valve", 1);
# new_class.addIntProperty("engines/engine[0]/augmentation-burner", 1);
# new_class.addIntProperty("engines/engine[0]/n1", 1);
# new_class.addIntProperty("engines/engine[0]/n2", 1);

#
#var bridgedTransmitter = emesary.Transmitter.new("outgoingBridge");
#var outgoingBridge = emesary_mp_bridge.OutgoingMPBridge.new("F-14mp",routedNotifications, 19, "", bridgedTransmitter);
#var incomingBridge = emesary_mp_bridge.IncomingMPBridge.startMPBridge(routedNotifications);
#var f14_aircraft_notification = notifications.PropertySyncNotification.new("F-14"~getprop("/sim/multiplay/callsign"));
#-----------
#
# That's all that is required to ship properties between multiplayer modules via emesary.
# property /sim/multiplay/transmit-filter-property-base can be set to 1 to turn off all of the standard properties and only send generics.
# this will give a packet size of 280 bytes; leaving lots of space for notifications.
# The F-14 packet size is around 53 bytes on 2017.2 compared to over 1100 bytes with the traditional method.
# property /sim/multiplay/transmit-filter-property-base can be set to a number greater than 1 (e.g. 12000) to only transmit properties
# where the ID is greater than the value in the property. This can further reduce packet size by only transmitting the emesary bridge data
#
# The other advantage with this method of transferring data is that the model is in full control of what is
# sent, and also when it is sent. This works on a per notification basis so less important properties could be
# transmitted on a less frequent schedule; however this will require an instance of the notification for each one.
#
# PropertySyncNotificationBase is a shortcut notification; as it doesn't need to received and all
# of the properties are simply set when the notification is unpacked over MP.
# So although the notification will be transmitted
