 * This class implements event->states matching algorithm.
 * The purpose of it is to find all the states that can handle given event.
 * The event should be handled first by deeper states, as such processing guaranties that
 * all transitions will remain within the parent.
 *
 * This is a breadth-first search that walks all the active states and pushes them to the
 * stack, which is eventually returned to the caller.
 *
 * In the event of parallel state with children,
 * this algorithm will push nodes in order from deep to shallow.
