Simple Pathfinding
Simple brute force path-finding.
Pawns takes a bit better path than the vanilla, but reduce performance. Not good for many colonists, animals, caravan or raiders, large or complex map.
Simply put, the vanilla uses two algorithms and they would switch by a distance(*) to the destination. The difference only appears when the pawn moving complex and long path. In short case, the result will same (probably).
