[documentation] Missing documentation in green state classes.
The two classes ConnectorStateConnectionCompositor and StateConnectorConnectionCompositor did not have any class documentation. I’ve marked them RED for now.
I am unsure if these classes are needed: They are similar to
ConnectorConnectionCompositor and StateConnectionCompositor,
respectively. It may the case that one of them is responsible for
drawing transitions from state to state, whereas the other is
responsible for connector to connector (or state) transitions.
Thus, it should be clarified whether these classes are needed and documented if so.
