A generic transition between any two state machine states. It defines some special labels that indicate things like epsilon transitions and that the label is actually a set of labels or a semantic predicate. This is a one way link. It emanates from a state (usually via a list of transitions) and has a label/target pair. I have abstracted the notion of a Label to handle the various kinds of things it can be.
