thanks for this tbx!
Unfortunately it didn't work out on the first run.
This is the error msg:
Spatial reference:

<type 'exceptions.RuntimeError'>: ERROR 999999: Error executing function.
Failed to execute (BoundingContainers).
Failed at Fri Nov 14 13:26:43 2014 (Elapsed Time: 4,00 seconds)
any idea?
