StateHandler not invoked

[vishalg0wda]

StateHandler does not get invoked if defined with primitive datatypes:

@StateHandler(state = STATE_LOCATION_RESOLUTION_REQUIRED)
public void onEventStateLocationResolutionRequired(boolean success, TinyMachine tm) {
    // Code does not flow here.
    if (success) tm.transitionTo(STATE_BINDING_SERVICE);
    else tm.transitionTo(STATE_FAILED_LOCATION_RESOLUTION);
}

...

mTinyMachine.transitionTo(STATE_LOCATION_RESOLUTION_REQUIRED);
mTinyMachine.fireEvent(true);

This is probably not a bug, but I believe it should be mentioned in the docs. Would definitely save someone else the time.

Aside: thank you for this wonderful library! We're using it extensively in our app. :)

Few more features would be great to have:

• Allowed transitions support, meaning to block transitions to new state which are not allowed
• Undo: support undoing last tranisitions
