[Paraview] [paraview] Cannot create object of type "vtkCSVImageReader"

[papa ndéné NDIAYE]

I finally found a working example:
https://github.com/daviddoria/vtkEllipsoidSource/blob/master/vtkEllipsoidSource.xml

I just had to remove the "double vector property" field in the xml. I think
I will start from it.

Great thanks,
papa
