  Check_distance_targeting is only called when distance_targeting_enabled is true. Otherwise,
  available_targets is called.  The following code is intended to generate a target list that
  properly accounts for range from each target during chain lightning.  On a very basic level, it
  starts at the original target, and then finds a path that will hit 4 more, if possible.  The
  code below randomly cycles through targets until it finds said path, or hits the maximum amount
  of attempts, in which it gives up and just returns the current best path.  I wouldn't be
  terribly surprised if Blizz did something like this in game.
