[Paraview] Live Annotation

[Dan Goldstein]

Thanks Berk,
   I am writing unstructured XML vtk files with 
vtkXMLUnstructuredGridWriter. So the question I have is does the
vtkXMLUnstructuredDataReader support the time steps information?
If so can you point me to the vtkXMLUnstructuredGridWriter function used 
to put the time step information in the data file. Or is this done at 
the cell level?

  Thanks again,

Dan
