[Paraview] Problem with custom time-aware reader

[Moreland, Kenneth]

The file series reader should already be maintaining that for you.  It should only be calling the foo reader's RequestInformation when the file name changes.

There are some subtleties about when the FileName changes.  For example, after vtkFileSeriesReader::RequestInformation finishes, the last RequestInformation called will be for the last file.  Typically you end up reading the first file first, so on that first call to RequestData vtkFooReader::RequestInformation will be called again for the first file.

Thanks for the explanation. So, I guess it shouldn't harm to add some code to prevent re-parsing the same file again in RequestInformation in case this->FileName hasn't changed since the last time RequestData has been called.
