[Paraview-developers] Time-varying data reader

[David E DeMarle]

To make uniformly increasing time denoted in numbered file sequences,
encapsulate your reader in a sub proxy of a vtkFileSeriesReader. See
readers.xml for numerous examples of that.

If you need nonuniform temporal spacing or need to improve upon the
file series reader's IO performance, make your reader supply temporal
information and respond to time requests appropriately in
RequestInformation and RequestData respectively. See
vtkTimeSourceExample for an example of that.
