[Paraview] ParaViewWeb, vtk filters python description

[Sebastien Jourdain]

If you managed to load your plugin (the C++ ParaView one) at startup,
then you will be able to use your filter as any other filter in
ParaViewWeb without using any ParaViewWeb plugin. Otherwise, the
python file that you are missing is in fact an XML file that list the
properties for each filters and sources inside ParaView.

PARAVIEW_src/ParaViewCore/ServerImplementation/resources/filter.xml

The labels without space are used as filter name and properties for
creating and controlling those filters...

Otherwise inside your ParaViewWeb plugin, you can provide a dictionary
as argument and just loop through its entry and set them in python.
