\section Combinatorial_mapDesign Design and Implementation History
-The code of this package is inspired by Moka, a 3D topological modeler mainly developed by Frédéric Vidil and Guillaume Damiand (http://moka-modeller.sourceforge.net/). However, Moka was based on Generalized maps (and not Combinatorial maps), and the design was not \cgal "compatible". Thus, Guillaume Damiand started to develop a totally new package by mixing ideas taken from Moka with the design of the Halfedge data structure package of \cgal. Andreas Fabri and Sébastien Loriot contributed to the design, the coding, and to the documentation of the package, and Laurent Rineau helped for the design. Emma Michel contributed to the manual. Monique Teillaud and Bernd Gärtner contributed to the manual by giving useful remarks, really numerous and detailed for Monique. Ken Arroyo Ohori contributed to the two reverse orientation functions.

The advantage of `min_max_element()` compared to calling both \stl functions is that
one only iterates once over the sequence. This is more efficient
especially for large and/or complex sequences.
