Detailed Description

A topological fingerprint of a tracked surface inside a tet mesh.

Cheap-to-compare summary used to assert that surface-modifying operations (surface edge flips) do not change the surface topology: number of connected components, surface V/E/F, Euler characteristic, and number of boundary loops. A valid surface diagonal flip leaves all of these invariant. O(#surface faces); only used by tests and by the check_surface_topology debug option.
