-- no one of the FT Layers are needed, they are just used for displaying the network stations and lines on the map.
-- ft_layer_ids.gtfs\_\* and ft_layer_ids.topology\_\* are mutually exclusive, the first one  should be used if the project is GTFS-based . Same for geojson.gtfs\_\* vs geojson.topology\_\* keys
