示例1: DoTurn

//searches a path that cannot be attacked in one turn, but that does not look whether another ant is in the way
//so the path is planned like all friendly ants do not exist.
Search search2 = new Search(state, state.GetDistance,
(Location location) => { return state.GetIsPassable(location) && !state.GetIsAttackable(location); });
//search for a path that takes in account where other friendly ants are, but does not look at enemy ants.

//and enemy ants may be moved.
