I may have spoken too soon :)

Certain combinations of input geometry cause my spheremaps to break. I am
relying on the assumption that shalfedges are arranged clockwise around
svertices, such that shalfedges linkage (via next()) is always in the same
direction. I'm finding that, in rare circumstances, this isn't the case.
Is it supposed to be?

I am always using new_shalfedge_pair(SVertex_handle v1, SVertex_handle v2)
to construct shalfedges, and was assuming that it was setting up all
incidences correctly.
