Try to calculate intersection points between polygon outer boundaries. Are 
able to iterate thru the curves and get them
as X_monotone_Cruve_2 or more exact:
  typedef CGAL::Exact_predicates_exact_constructions_kernel Kernel;
  typedef CGAL::Gps_circle_segment_traits_2<Kernel>         Traits_2;
  typedef Traits_2::X_monotone_curve_2                      
X_monotone_curve_2;

Are also able to create an intersector with:
  CGAL::Arr_circle_segment_traits_2<Kernel> t2;
  auto intersector = t2.intersect_2_object();

Then trying to use the intersector with:
  std::list<Apoint_2> pts
  CGAL::intersection(intsegments.begin(), intsegments.end(), 
std::back_inserter(pts));
I however get a compiler error about the iterator. Tried diferent types for 
the point:
  typedef Kernel::Point_2                                   K_Point_2;  
  typedef Traits_2::Point_2                                 Apoint_2;
  typedef Polygon_2::Point_2                                P_Point_2;
But all without success. Anybody have a clue what might be wrong?
