A great deal of the complexity of the current code is that we must chain 2 reactive values (one in the map "GameScene.MapPlayersByKey" and one in the snapshot store). The new generic MapStore class can be used to listen to stores inside a map. When the store inside the map, or the map itself is modified, the resulting store is updated.
