since that's the only game-related generic function that use
synthesis_info.

Introduce a new, uniform way to create and solve
games.
Games can now be created directly from specification
using creat_game, uniformly solved using
solve_game and transformed into a strategy
using create_strategy.
Strategy are mealy machines, which can be minimized.
