| SurfaceMeshContourIxer | An intersector which produces contours, similar to AJL's code. | 
| SurfaceMeshContourIxer.EdgeFacePair | Static Inner Class for holding an Edge-Face pair. | 
| SurfaceMeshIntersector | A collider that determines the intersection between two meshes by first
 identifying and tracing the intersection contours between the meshes, and
 then using these to determine the interpenetration regions. |
