  16 # A screen is a function which instanciates all components of a screen into a temporary component.
  17 # Thus, the global stuff is a screen, too.
  18 # In a screen, components can either be instanciated from the class-tree, cloned (copied) or
  19 # "linked" from the instance tree.
  20 # A screen itself lives as the container of the components, so a screen is a component, too.

  23 # and one with the instanciated components itself (both global and dynamic)
