pub fn certify_face_within(
    model: &Model,
    face: &Shape,

    tol: Tolerances,
) -> OgeomResult<Result<(), Uncertified>>

Whether every point of face stands within fit of region: Ok(()) when proved, else what kept it from being proved (see the module documentation for the argument and its one input from the mesher).
