[vtkusers] Cutting 3D isosurface

[Isaiah Norton]

I've looked into this a little bit for a similar application, and I think
the key thing is to look at the classes deriving from vtkImplicitFunction to
see if there is one that gives the desired deformation, or subclass to suit.
vtkClipPolyData can take any of these as input.
