DijkstraShortestPath Check method should be used or removed #11
Description
The DijkstraShortestPath class has a Check method that is currently only used by unit tests.
https://github.com/FaronBracy/RogueSharp/blob/master/RogueSharp/Algorithms/DijkstraShortestPath.cs#L153
It was originally intended to be a private method and called from the bottom of the constructor.
Investigate if this method is useful or not. If it's not get rid of it. If it is useful consider making it private and make the class use it where appropriate.
