Bevel Operator: First pass at custom profile functionality in 'pipe' vertex mesh
case with two nearly parallel incident beveled edges. This attempts to reuse the
profile at each vertex in the mesh by intersecting the original profile with a new
plane at the current vertex's ring in the vmesh.

It currently works, but only for a portion of the vertices in the vmesh, which
suggests problems with the vmesh NewVert indexing
