Voronoi.charge on # on|off, default = off
In case of a methane molecule, the following Voronoi charges are output to 'System.Name.out'.

However, the Voronoi analysis could be a useful and complementary information for a bulk system with a closed pack structure. Also, the Voronoi volume being a supplemental information will be useful to analyze local structure for bulk systems.
