Assuming that I am not changing a Polyhedron_3 data structure with any topological operations, will I always get the same edge when calling vertex_begin()? Given a vertex I need to consistently identify a "first" edge incident on it. vertex_begin() would serve this as long as it always returns the same edge. What are the guarantees? Can a similar thing be asserted about vertex->halfedge()? I just need to consistently get the same edge.
