Nav3DPath: Events

For the convenience of notification when the pathfinding finished, the following events have been implemented:

• public event Action<PathfindingResult> OnPathfindingSuccess – triggers when pathfinding finished successfully.
• public event Action<PathfindingResult> OnPathfindingFail – triggers when pathfinding ends with failure.
• public event Action<PathfindingResult> OnPathfindingComplete – triggers in both cases.
