11 # In a screen, components can either be instanciated from the class-tree, cloned (copied) or
12 # "linked" from the instance tree.
13 # A screen itself lives as the container of the components, so a screen is a component, too.
15 # we thus have one (static) hierarchy of screens (classes, not instances)
