Instead of writing TODO comment blocks, just do the work, and move the function to the proper class. Further, after review from Berthold, cleanup the function. There is no reason that getGasList() is member of any class. It is just a non-class helper, and as it is only used here, a static helper. Signed-off-by: Jan Mulder <jlmulder@xs4all.nl>
