ChangePathNode(path table, PathNode, [X],[Y],[Z],[Delay],[Flag],[function called],[delayed function])   -> Changes the properties of the PathNode, but only the given ones and returns true if successfully changed or false if failed.

AddPathNode(path table, PathNode, X, Y, Z, Delay, Flag, function called, delayed function)              -> Adds a new PathNode to the table with the given informations and returns true if successfully added or false if failed.
