Experiments in pathfinding for Illy using the ngraph library written by anvaka.
Cost of movement between tiles is based on the combat terrains and rather
than have to fetch all that from the server all the combat terrain info is
stored in a hidden bitmap (it takes a few secs to load initially but much
faster than waiting on my slow server for each path).
A major part of this current experiment is playing with the adjustments
of how difficult each terrain is to travel through. In the future I may look
at also incorporating boime information in this difficulty (jungle is much
harder to cross than plains).
