That is a followup of the following two commits. The "polyline CDT" has
been branched from CDT before those patches were in CGAL:
| commit 49404f75f5
| Author: Laurent Rineau <Laurent.Rineau__CGAL@normalesup.org>
| Date: Thu Jun 28 09:16:23 2012 +0000
|
| Improved patch
|
| The Constraint_hierarchy is now templated by T, an anonymous type (that is
| a Vertex_handle when the constraint hierarchy is used in Ct_plus_2), and a
| Compare operator, that have a comparison member function:
| bool operator()(T, T);
|
| In Ct_plus_2, the Compare operator passed to the Constraint_hierarchy
| compares the vertices with a Less_xy_2, implemented by Less_x_2, and
| Less_y_2.
|
| The test test/Triangulation_2/include/CGAL/_test_cls_hierarchy_2.h has been
| tweaked, to check that the type T passed in the hierarchy no longer needs
| to have a point() member function, as it was before May 2010 (when GF has
| determinized the Cdt_plus_2 using too simple patch).

| commit 7cb640d05d
| Author: Andreas Fabri <Andreas.Fabri@geometryfactory.com>
| Date: Mon Jun 25 10:11:56 2012 +0000
|
| The Constraint_hierarchy_2 gets an additional LessXY_2 functor as template argument so that it no longer applies operator<(Point,Point)
