  11 # A screen is a function which instanciates all components of a screen into a temporary component.
  12 # Thus, the global stuff is a screen, too.
  13 # In a screen, components can either be instanciated from the class-tree, cloned (copied) or
  14 # "linked" from the instance tree.
  15 # A screen itself lives as the container of the components, so a screen is a component, too.
  16
  17 # we thus have one (static) hierarchy of screens (classes, not instances)
  18 # and one with the instanciated components itself (both global and dynamic)
