bool OEMakeCliqueSurface(OESurface &newsurf, const OESurface &surf,
                         unsigned int clique)

Creates a new surface in newsurf from the triangles in surf marked with the vertex clique value clique. Zero is not a valid clique. See the Cliques section on how vertex cliques are assigned to triangles. See the Surface Subsets section for an explanation of how Spicoli handles subset boundaries. Returns true if successful.
