Custom ME Aircraft Properties

-- To add a custom properties tab to aircraft in the Mission Editor, add the following structure within the aircraft definition in the aircraft lua.

AddPropAircraft = {
    { id = "CheckboxPlaceholder" , control = 'checkbox', label = _('Checkbox Placeholder'), defValue = false },
    { id = "MassChangePlaceholder" , control = 'checkbox', label = _('Mass Change Placeholder'), defValue = false, weight = 500},
    { id = "CombolistPlaceholder" , control = 'comboList', label = ('Combolist Placeholder'), defValue = 0,
        values = {
            { id = 0, dispName = _("ITEM1")},
            { id = 1, dispName = _("ITEM2")},
            },},
    { id = "SliderPlaceholder", control = 'slider', label = _('Slider Placeholder'), defValue = 90, min = 0, max = 100, dimension = '%'},
},

-- To read these properties in LUA:
get_aircraft_property("<PROPERTY_NAME>")
--returns an integer of the option value (0 or 1 for checkbox and 0 based index of combolist option)

-- To read these properties in C++ (Two methods):
-- EFM functions:
