> Implement the existing todo in Automaton.step() (lookup a transition from a source state depending on a given label) to use binary search since the transitions are sorted.
> Introduce new method Automaton.next() to optimize iteration & lookup over all the transitions of a state. This will be used in RunAutomaton constructor and in MinimizationOperations.minimize().
