Adding a new class: PathFinding.h/cpp
Adding a usable but unfinished AI which uses the pathfinding class: goToPlayerAI() in NPCHandler.h/cpp. The AI function uses an additonal function findPlayer() and a bunch of global field variables. Modified Source.cpp to create a test npc.
Illegal node initalization fixed; moved to node constructor. Constructor needs to be moved out of .h still though. I didn't notice this problem until Mike pointed it out since I'm using toolset v120 to compile.
