[Paraview] python script for plot-over-line filter

[Utkarsh Ayachit]

Jade,

Here's the link to the Wiki about saving CSV files:
http://www.paraview.org/Wiki/ParaView/Python_Scripting#Exporting_CSV_Data

In short, the following script should do it:

>>> writer = CreateWriter(".../foo.csv", source)
>>> writer.FieldAssociation = "Points" # or "Cells"
>>> writer.UpdatePipeline()
>>> del writer
