Expose stop() method

[millette]

I'm using finity with react and I need to stop the FSM when a component will be unmounted.

I figured a few ways to call the internal stop() method but they seem a bit hacky. Could we expose the stop() method, the same way start() is available?

Or do I need a custom "stop" event and handle it that way?

@millette I considered exposing stop() but decided against it because of some corner cases. I agree that stop could be useful though. Let me look into this again.
