method for finding a Nash equilibrium.
- Additional game transformation operations have been moved to the Game class, and old versions
deprecated.
+- Accessing payoffs of outcomes and pure strategy profiles is now standardized to use player
+ references, and accessing by index has been removed.
- Game.num_nodes has been removed in favor of Game.nodes, which returns a list of the nodes
in the game.
