+   * \brief HOMARD method of hexahedron quality
+   * 1. Decompose the hexa into 24 tetra: each face is splitted into 4 triangles by
+   *    adding the diagonals and every triangle is connected to the center of the hexa.
+   * 2. Compute the quality of every tetra with the same formula as for the standard quality,
+   *    except that the factor for the normalization is not the same because the final goal
+   *    is to have a quality equal to 1 for a perfect cube. So the formula is:
+   *    qual = max(lengthes of 6 edges) * (sum of surfaces of 4 faces) / (7.6569*6*volume)
+   * 3. The quality of the hexa is the highest value of the qualities of the 24 tetra
