[vtkusers] show differences of two ensight formated files

[Fabian Braennstroem]

Hi,

I would like to compare two results in ensight format at a
given plane, i.e. I show on one plane the reference data and
on the other plane the differences.
For this I have to subtract two reader or assign outputs; I
would say. Is there a function to do that or do I have to
subtract every data point from each other and apply it to a
new cutter input?
Would be nice, if you have any suggestions!

Greetings!
 Fabian
