[Paraview] Python Programmable Filter

[Utkarsh Ayachit]

No, it's not possible to write a python programmable filter with
multiple output ports. The number of output ports needs to be set in
the constructor of the class itself which is too early to be able to
set by the user from the panel for any filter. Workaround is producing
a multi-block.
