Solves your rush hour puzzles.

For example:

python3 rushhour.py --game 2 --bfs

Runs game2 with breadth first search.

We have two a* heuristics. For the most simple A star heuristic:

python3 rushhour.py --game 2 --astar --depth 1

The other A* heuristic, searches for blocking cars one level deeper:

python3 rushhour.py --game 2 --astar --depth 2

For the interactive freezing algorithm, use:

python3 rushhour.py --game 7 --interactive
