We could create one elevator-node for each level the elevator connects
to. These nodes are only connected to the ways on their level. This
basically results in the elevator access points (aka doors) are mapped.
To find out which elevator doors belong to the same elevator we can put
all the nodes in a relation. Please note that this scheme would not only
work for elevators but also for teleporters.
