mesh (initiator-shadow)
This tag is only compulsory if you have a initiator-shadow container.
When a "initiator-shadow" container is contained in the mesh-table for a bridge config file, it is the kuid/kuid2 for the starting mesh of the bridge. This is the shadow for the first section of the bridge that will be drawn Trainz surveyor.
