recursion in Class-methods?

[Roopesh]

Wrong:
newpath = find_path(self.dictionary, node, end, path)
newpaths = find_all_paths(self.dictionary, node, end, path)
newpath = find_shortest_path(self.dictionary, node, end, path)

Correct;
newpath = self.find_path(self.dictionary, node, end, path)
newpaths = self.find_all_paths(self.dictionary, node, end, path)
newpath = self.find_shortest_path(self.dictionary, node, end, path)
