computeCutFill MethodStatic

• Split facets into vertically overlapping sections
• both meshes are represented by visitors rather than the meshes themselves
  • If the data in-hand is a mesh, call with mesh.createVisitor
• The respective clip parts are returned as separate meshes.
  • Caller may set either or both builders to toggle facet order (e.g. toggle the lower facets to make them "point down" in cut-fill application)
• Both polyfaces are assumed convex with CCW orientation viewed from above.
• Each output contains some facets from meshA and some from meshB:
  • meshAUnderB -- areas where meshA is underneath mesh B.
    • If A is "design surface" and B is existing DTM, this is "cut" volume
  • meshAOverB -- areas where meshB is over meshB.
    • If A is "design surface" and B is existing DTM, this is "fill" volume
