Laying out the windows in the window manager frame, is a very similar process regardless of doing it horizontally or vertically. So the template design pattern was applied and the general functionality was pulled up; only specific functionalities were put into the corresponding classes. kNCursesDemoApp: Separated the screen into three windows vertically. The top and bottom window contain another two windows each, lay out horizontally. The top left window is fixed to width 1 and the top right takes the rest of the space. Bottom two windows take 50 % of the space each. Remarks: There are still some rendering bugs, when hiding and showing windows. E. g. when hiding the top or middle window with `<F1>` or `<F2>` respectively, the bottom window has some errors. Maybe some timing issue.
