[Paraview] Python Programmable Filter Time Series Source

[Bane Sullivan]

Here is an example of a programmable filter vis XML that I want to simply
print off the various file names or give me and ability to read the file
series. I have this python programmable filter set up to work when I click
File->Open in ParaView. I have the ability to then chose file series from
the file prompt. How might I make a programmable filter via XML attributes
so that it can handle file series.
