Cutting planes in 3D Slicer 4.6

@lassoan Would you be able to provide usage help for the module? Or only development help for updating the module to work with Slicer 5.0.3?

There was some previous request for help on how to install and run the module, but there was not a response at How to run · Issue #1 · PerkLab/SlicerSkinMouldGenerator · GitHub.
