[Paraview] Switching Between Readers

[Dean, Kevin]

I was wondering if there was a way to instantiate a superclass that, let's
say, can switch between vtkPolyDataAlgorithm and vtkImageAlgorithm.

I have a reader that (as of now) converts the data within a protobuf file
to image data.

But currently, I have multiple protobuf files with different information.
However, the file extension is still .pbuf, and it seems that the reader
xml parsers the files based off this input.

So would it be easier to change the filename? Or is there a way to switch
between the two algorithm classes?

Thanks for your time!
