@HenriDeh Ready to go (I hope)! Had to add three new objects AbstractPlayer, Player, PlayerTuple to deal with type ambiguities between actions / states and players, when actions / states use Symbol type.

[HenriDeh]

a few remarks otherwise great job !

[jeremiahpslewis]

One more thing...ComposedStop was creating all kinds of type stability issues, for little gain; it takes 4-5 lines to define a custom ComposedStop with your favorite reducer. So I dropped it, we now have StopIfAll and StopIfAny; if there's a third really popular one, it can go in the 🐮 🐷 🐔 Farm, but for now we cover 90% of typical usage. ;) @HenriDeh

@HenriDeh Thanks for the thorough review and helpful comments, the PR got a bit out of hand towards the end!
