Q1: Present proof of A* Amissible using Paceman's example.
Search: Mr. and Ms. Pacman

alternate turns. You must devise a plan which positions them together,
somewhere, in as few time steps as possible. Passing each other does not count
as meeting; they must occupy the same square at the same time.
