[Paraview] Saving data plotted using PlotOverLine

[Stephen Molloy]

Thanks for the tip.  That writes a CSV file, but it's much shorter than 
the one written by "Save Data".

The following is my python file.  Perhaps someone could comment on how 
it should be altered so as to correctly save the entire PlotOverLine 
dataset?  (One thing I notice is that the settings controling the number 
of points in the line don't seem to appear in the trace either -- 
perhaps this is the cause of my troubles?)
