The dangerous implicit conversions between weighted points and points
have been disabled. The constructors used to build a weighted point from a point
(and reversely) are still available but must be called explicitely.

<h3> 2D and 3D Triangulations </h3>
<ul>
<li><b>Breaking change</b>:
Added a new functor requirement, Construct_point_2, to the concepts
TriangulationTraits_2 and RegularTriangulationTraits_2 and a new functor
requirement, Construct_point_3, to the concepts TriangulationTraits_3 and
RegularTriangulationTraits_3. Note that all models of the concept Kernel
already provide these functors.
Added a new functor requirement, <code>Construct_point_2</code>, to the concepts
<code>TriangulationTraits_2</code> and <code>RegularTriangulationTraits_2</code>
and a new functor requirement, <code>Construct_point_3</code>, to the concepts
<code>TriangulationTraits_3</code> and <code>RegularTriangulationTraits_3</code>.
All models of the concept <code>Kernel</code> already provide these functors.
</li>
<li><b>Breaking change</b>:
The concept RegularTriangulationCellBase_3 must now define a 'Point' type
instead of a 'Weighted_point' type. This is only a name change to
align RegularTriangulationCellBase_3 with other similar concepts and this
type must still be the same as the point type `Weighted_point_3` defined
by the geometric traits class of the triangulation.
Introduced the concept <code>RegularTriangulationVertexBase_3</code>. This
concept describes the requirements for vertices meant to be used in regular triangulations.
Concepts that previously refined <code>TriangulationVertexBase_3</code>
but modeled a vertex class used in regular triangulations, such as the concept <code>MeshVertexBase_3</code> in the 3D mesh
generation package, now refine <code>RegularTriangulationVertexBase_3</code>.
<li><b>Breaking change</b>:
Uniformized the point type defined in the vertex and cell concepts. The triangulation
point is now always <code>Point</code> (note that this is either a <code>Traits::Point_[23]</code>
for basic and Delaunay triangulations or a <code>Traits::Weighted_point_[23]</code> when considering
regular triangulations). Consequently:
<ul>
<li>
The concept <code>RegularTriangulationVertexBase_2</code> now requests
a <code>Point</code> type (equal to <code>Traits::Weighted_point_2</code>)
</li>
<li>
The concept <code>RegularTriangulationCellBase_3</code> now requests
a <code>Point</code> type instead of a <code>Weighted_point</code> type.
</li>
<li>
The concept <code>DelaunayTriangulationCellBase_3</code> now requests
a <code>Point</code> type instead of a <code>Point_3</code> type.
