Author: Rod Green

Description
A text book implementation of the A* network pathing routine. Based of the wikipedia detailing on the method. A* Wikipedia Article

Usage
The code is broken into a class (AStarHelper) and the base interface (IPathNode) needed for the Helper class

See below for usage example (tester).

Usage Example
This is a very quick and dirty implementation of the AStartHelper class. It's really meant to allow fast debugging of the routine and not a 'true' implementation of the technique into a game library.
 * PathNode class (MonoBehaviour) is an implementation of the IPathNode interface
 * PathNodeTester (MonoBehaviour) is an object that's used to handle the globals and execution of the path calculations
