Adding and wrapping a custom namespace within VTK

That’s exciting! Will this handle enums and enum classes embedded in another class? That’s the only thing that is failing for me right now here, with those errors:

  • enum: vtkAnatomicalOrientationPython.cxx:444:22: error: use of undeclared identifier 'Axis'; did you mean 'vtkAnatomicalOrientation::Axis'?
  • enum class: vtkAnatomicalOrientationPython.cxx:118:16: error: no matching function for call to 'PyvtkAnatomicalOrientation_Axis_FromEnum'

Apart from that, it looks pretty good, thanks for the help:
