  + * A weighted version for Alpha complex is available (cf. Alpha_complex). It is like a usual Alpha complex, but based
  + * on a <a href="https://doc.cgal.org/latest/Triangulation/index.html#title20">CGAL regular triangulation</a> instead

  * This example builds the CGAL weighted alpha shapes from a small molecule, and initializes the alpha complex with
  * it. This example is taken from <a href="https://doc.cgal.org/latest/Alpha_shapes_3/index.html#title13">CGAL 3d
