I've made quite a lot of changes in the pathfinding article in our wiki. I'd appreciate if someone could take the time to review it and spot my possible mistakes, in particular in the implementations of BFS, Dijkstra and A*
I wanted this article to be readable and immediately understandable by beginners, so please tell me if it ain't so
