[vtkusers] Animation of multiple input files in VTK

[Dominik Szczerba]

There are a few possibilities. The simplest would be to update the
reader in a loop and dumping screen renderings. More sophisticated
would be to import them first into a temporal dataset and then request
a specific time value.
