Strict mode

[MicheleBertoli]

Add a strict option which makes the component throw an exception if the current state doesn't support the action.

withStateMachine({ config, strict: true })(App)

Or if a state isn't represented within the component? 😇

@MicheleBertoli I can also add strict mode to error for undefined state transitions in xstate version 2 if that's desirable.

Currently (in the beta), .transition(state, unhandledAction) will return undefined.

Oh yeah @ctrlplusb, thanks for your comment.
I was thinking about "registering" the State components to the parent, in order to double check that all the states are covered.

That'd be great, thank you very much @davidkpiano.
The current beta behaviour with the undefined state makes it easy to throw an exception within this package.
However, I believe xstate users would benefit from a strict mode as well and the more react-automata is just a React/UI layer on top of existing xstate features, the better.

Fixed in statelyai/xstate#23
