[Paraview] Python Script - access the raw data loaded from a dataset and creating new dataset (UNCLASSIFIED)

[Burlen Loring]

Hi Simon,

Fetching the data to the client is generally a bad idea. Instead you 
could use a python programmable filter which allows you to operate on 
the data in place on the server side.
