* \class QuadEdgeMeshTopologyChecker
* \brief Make some basic checks in order to verify that the considered
* mesh is not degenerated and correctly represents a surface
* with a potential boundary.
*
* We check that they are no isolated vertices, no isolated edges and
* that the Euler formula is possible.
