[Paraview] Readers

[Berk Geveci]

Hi Randy,

You should restructure your code a little. You should not be setting
the output directly. Instead you should probably shallow copy the
internal data object (aVTKUGSetup I think) to the output created by
the superclass. You can look at any subclass of
vtkUnstructuredGridAlgorithm in the Graphics directory to see how to
get the output. To fully experience the new pipeline, you can also use
RequestData() and RequestInformation() as most new algorithms now do.
I believe one of the newsletters talk about the new pipeline
