# A screen is a function which instanciates all components of a screen into a temporary component.

# "linked" from the instance tree.
# A screen itself lives as the container of the components, so a screen is a component, too.
# we thus have one (static) hierarchy of screens (classes, not instances)
# and one with the instanciated components itself (both global and dynamic)
