 # Services related to pathfinding of graphs using A*
 # A single graph may have different properties according to the `PathContext` used

+#
 # Usage:
 #
-#    # Weighted graph (letters are nodes, digits are weights):
-#    #
-#    #     a -2- b
-#    #    /     /
-#    #   3     1
-#    #  /     /
-#    # c -3- d -8- e
-#    #
-#    var graph = new Graph[Node,WeigthedLink[Node]]
