[Paraview] Calling a customized xml plugin from python

[Utkarsh Ayachit]

Oh, I think I error is this:

   LoadPlugin(.., ns=globals())

The namespace is the 3rd argument for LoadPlugin[1], not second.  So
either use the proper location, or use the keyword argument.

The strange thing is that if there is some error while running script (for example, reading empty arrays), then myfile() is not recognized anymore, unless I restart the python interpreter (not necessarily paraview), but I was not really able to isolate the issue (I am just restarting the shell to make it work)
