| CostEvaluator In order to make the solving of shortest path problems as general as
 possible, the algorithms accept objects handling all relevant tasks regarding
 costs of paths. | 
| EstimateEvaluator Evaluator used to estimate the weight of the remaining path from one node to
 another. | 
| PathFinder Interface of algorithms that finds paths in between two nodes. | 
| WeightedPath A  Paththat has an associated weight. |
