   This is a plasma applet that provides a countdown and a stopwatch.
   The countdown could be started anonymous or with a preset.
   The anonymous countdown asks for hours, minutes and seconds after
   which the could down should be finished.
   The Presets could be configured and used to e.g. count down the
   time to cook pasta or make a tea.
