Again following up in my thread of non-manifold Nef3 decoration. This has
become quite a bit more technical than it should for this forum. I'm
posting an update just for consistency's sake.

What I found that I had to do to guarantee consistent
halfedge_around_vertex adjacency ordering when constructing spheremaps in
non-manifold situations was add another overload to SM_decorator in the
form:
SHalfedge_handle new_shalfedge_pair(SVertex_handle v1, SVertex_handle v2,
const Sphere_direction sd)
