[Paraview] Example project: vtk libraries, python wrappers, paraview plugin

[Pat Marion]

Hi,

I wanted to setup a project that built VTK libraries using the modern vtk
module cmake code, added Python wrapping to the VTK libraries, and then
built a ParaView plugin that linked against the VTK libraries.

Traditionally, a ParaView plugin is created by compiling all the cxx files
into the plugin library, but I wanted my files compiled into a standard VTK
module library, and I wanted Python wrappers so that I could import my vtk
module library in Python.

Here's the example project.

It works, I tested it on ParaView master, but I had to comment out some
lines in ParaViewPlugins.cmake to avoid configure errors.  If a someone who
knows the pv_setup_module_environment() macro wants to give this a shot and
see why it doesn't work, please let me know!  *It seems that
pv_setup_module_environment() is broken:*

CMake Error at ParaView/VTK/CMake/vtkModuleAPI.cmake:44 (message):
  No such module: "AutobahnPython"
Call Stack (most recent call first):
  ParaView/CMake/ParaViewPlugins.cmake:1300 (vtk_module_load)
  Module/CMakeLists.txt:2 (pv_setup_module_environment)


I had to comment out a foreach loop to make it configure:

diff --git a/CMake/ParaViewPlugins.cmake b/CMake/ParaViewPlugins.cmake
