1. Multiple changes in ShapeUpgrade_ShapeDivideArea, ShapeUpgrade_FaceDivide, ShapeUpgrade_FaceDivideArea, ShapeUpgrade_SplitSurface, ShapeUpgrade_SplitSurfaceArea: new methods NbParts and SetSplittingByNumber, changes in ShapeUpgrade_FaceDivideArea::Perform and ShapeUpgrade_SplitSurfaceArea::Compute concerning new modes of splitting. 2. New Draw command "DT_SplitByNumber" for testing new modes of splitting. 3. New subgroups "split_number" and "split_two_numbers" in the group of tests "heal" for testing new modes of splitting.
