public class GridStatistics0
Used by Grid2DSquareCellAbstract instances to access statistics. This class to be instantiated for Grid2DSquareCellAbstract that keep all statistic fields up to date as the underlying data is changed. (Keeping statistic fields up to date as the underlying data is changed can be expensive.)
