[vtkusers] Temporal Interpolation Assistance with VTK7 in Python

[David Thompson]

Hi Andrew,

I don't know whether the Exodus reader itself or the FileSeries reader does it, but one of the two should identify the files as a time-sequence. Note that usually Exodus time-series are broken into multiple files at steps where mesh adaptation occurs. Time *interpolation* (i.e., generating a mesh at a time between 2 saved steps) cannot take place at this boundary since there's no registration between the meshes.
