==== UBIK-UID Tag ====
Just like the UBIKObjectAction, this action allows the usage of a optioanl optional UBIK-UID tag, specifying the ID of a UBIK object.
If it is specified, the respective object is linked to this geometry; else, it is tried to find an object with a marker classification and the geometry action's tracking ID for it's marker id value.
When the user clicks on the geometry, a dialog is opened for the linked object (if found).
