Hi there,

After meshing (either with Constrained_Delaunay_triangulation_2 or
Constrained_triangulation_plus_2) I would like to be able to determine which
constraint an edge originated from, if any, but as yet have not been able to
see how.

I know how to test if an edge is constrained in general, but not due to
which one.

I have also noticed the insert_constraint method of
Constrained_triangulation_plus_2 returns a Constraint_id, but I can't see
how get this id from an edge.

Any pointers would be greatly appreciated,

Erik
