[Paraview] [Update] [Example files] To create a snapshot from a given datafile and state, how to change the datafile filename of the state?

[Utkarsh Ayachit]

I wouldn't go about loading the state again and again merely to change
the filename, instead change the filename directly on the reader
proxy.

Use GetSources() to get a map of all the sources in the state. Looking
at the names, you should be able to figure out what's the reader
proxy. Then you can change the FileName on it.
