* Class that keeps track of the costs, so you can request how much a block of

 *  commands did cost in total. Works in both Execute as in Test mode.

 * Example:

 *   {

 *     local costs = AIAccounting();

 *     BuildRoad(from_here, to_here);

 *     BuildRoad(from_there, to_there);

 *     print("Costs for route is: " + costs.GetCosts());

 *   }
