A MappedinVortex is a special entity that represents a link between two or more MappedinMaps at a given MappedinVenue. It is typically something like an elevator or stairs. These are also known as Connections in some parts of the system.
They can be marked (wheelchair) Accessible or not for pathfinding purposes. If you ask for Accessible directions, paths that include non-accessible Vortexes like Stairs will not be used.
