[Paraview] particletracer, vectors menu?

[John Biddiscombe]

OK. I didn't read all your message.

TemporalStremTracer actually expects a vtkTemporalDataSet as input, but 
the LEA test data is a series of vti files and the generic reader in 
PraaView does not export TIME_RANGE so the executive won't allow it to 
be used as a temporal dataset.

I can make available another test (3D) dataset if it will help
