[vtkusers] VTK File with Multiple Wariables ASCII to Binary Problem

[Gerard Gorman]

Basically what's happening is that when you do a GetOutput() only the 
active SCALAR, VECTOR and TENSOR get passed back from 
vtkStructuredGridReader/vtkStructuredGridWriter. Try printing out 
fileIn.GetOutput()

My own experience is that vtkXML...GridReader/vtkXML...GridWriter are 
much handier because it classifies all non-active SCALARS/./. as arrays 
and everything gets passed along nicely.
