A star search algorithm, 1 file, no additional functions. Well explained and easily expandable/re-usable.
Change the map, starting points, and obstacles as pleased.
Heuristic weight can be changed to be greedier or set to 0 to obtain Dijkstra algorithm.

Blue plotted nodes are part of open set.
Green plotted nodes are part of closed set.
Red plotted nodes show the final path.
