[Paraview] Attempting to run Catalyst CFullExample

I did provide the script as an argument (following the instructions
at the top of the python script).

I'm not quite sure what you mean by "ParaView versions of the python
script".  I do know that when I compiled the simulation with the
Catalyst code, I am pointing to the same version of ParaView that
I'm running.  I don't know how that correlates to python versions.

Well, thought I was downloading his latest examples by grabbing
them directly from his github page.  Is there somewhere else to
look for them?  Most of the files are dated May 13, 2013.

Not yet, but if you could explain what you mean by the ParaView
python version, that might shed some light.  I know I'm using the
same version of ParaView.
