 * Create a Transition table to describe the rules for state transitions. For convenience, the
 * DefaultTransition creates transitions based on a pattern, in this
 * case: <CURRENT_STATE> + <INPUT> = <NEXT_STATE>. If you'd like to use a different pattern,
 * you can pass a regex to DefaultTransition::usePattern(...) to substitute your own. The only
 * hine must implement the Stateful interface. For
 * convenience, the StateMaintainer trait is available to satisfy the bare minimum
