get_shortest_routes($from, $to)

Expects 'from' and 'to' station name and returns an object of type Map::Tube::Route. On error it returns an object of type Map::Tube::Exception.

get_all_routes($from, $to)

Expects 'from' and 'to' station name and returns ref to a list of objects of type Map::Tube::Route. On error it returns an object of type Map::Tube::Exception.

Be carefull when using against a large map. You may encountered warning as 'deep-recursion'. It throws the following error when run against London map.
