Fork Node
A Fork node is a node that represents forking (splitting) of control in a model. A Fork has one incoming Succession and multiple outgoing Successions. All outgoing Successions are triggered when the incoming Succession is triggered. The actions connected to
the outgoing successions cannot start until the action connected to the incoming succession has completed.
