Started smarter dracAI, working on implementing closest hunter and moving away from that hunter.
Using graph.c functions to find closest hunter.
Dracula AI with ability to tell which hunter is closest (by road only at the moment) and move to a location that maximises the distance between Dracula and that hunter. Some changes to graph.c and graph.h to allow for this.
