In the source code there are two classes, Point and Edge. A series of points
are stored in a std::multiset. Edges are formed between the points, referenced
by multiset iterators. The points are given pointers to the edge they are a
part of.
In the function Edge::splitEdge, an edge is broken up by a new point. The
point is added to the multiset, a new edge is created, the edge's iterators are
reset, and the Edge pointers are reset.
When resetting the Edge pointers, the compiler is insisting that the data
contained in std::multiset<Point>::iterator is a const Point.
If I change the Point member data Edge *dp_edge to mutable and make the
Point::setEdge function const, the code compiles.
