docs: Import the reference of the given refobj
  
          Here we assume, that the reference is already in the scene and
          we break the encapsulation and pull the data from the reference into
          the current scene.
          This will call :meth:`ReftypeInterface.import_reference` and set the
          reference on the refobj to None.
  
          :param refobj: the refobj with a reference
          :type refobj: refobj
          :returns: None
          :rtype: None
          :raises: None
