Transition class abstract

Represents a transition in a state based view workflow.

The transition connects the two State's identified by their IDs, allowing a unidirectional traversial from source to target state. To simplify the definition of transitions, it is possible to summarize multiple transitions to one target. This type cannot be instantiated, instead the sub types ActionTransition and TriggerTransition should be used.
