[Paraview] 3D contour maps

[Cory Quammen]

Is there any connectivity information between the slices? If so,
you'll have to include this in the VTK file. If not, then you'll need
to either figure out how to add connectivity information, or you'll
have to probably create a new VTK class to create a surface between
the individual contours, and then create a plugin for ParaView to
expose that class. I'm not aware of anything in VTK that can do this
currently. Obviously, this is much more work and more difficult.
