Summary
This is a two part solution. Part one - solve the maze using techniques seen in previous days including use of a thread pool to arrive at a solution. Part two - iterate over the maze space (minus the outer ring) and attempt to "cheat" at that point. If the cheat makes sense, that is it cuts between two points in the solution either east-west or north-south, then add it to a map of cheats keyed by the cheat savings.
