on_enter_{state} does not excute automatically

[ExpandOcean]

I found on_enter_{state} excute only if I set the on_enter=xxx in defination of state. I think the code below is natural, but it can not work. Do you think it should be supported?

It wouldn't take much work to add that behavior, but I'm not sure how I feel about it. Mainly I worry about feature creep if we start doing things like scanning the data model for already-defined callbacks, etc. It feels a bit inelegant to me to push some of the FSM logic into the data object. That said, I don't feel strongly about it, so let's leave this issue open for now, and if other people weigh in with strong opinions one way or the other, we can re-evaluate.

+1 I think it would a great idea for on_enter_ and on_exit_ methods to be detected in the model and executed during transitions, Methinks it would make the code a whole lot more readable

Okay, then I'm sold. Does someone want to take a stab at a PR? If not, I should be able to get to it in a few days.

I'll do it and send you a PR
