SYNOPSIS
     use Map::Tube::Vienna;
     my $obj = Map::Tube::Vienna->new;
     my $routes_ar = $obj->get_all_routes($from, $to);
     my $station = $obj->get_node_by_id($station_id);
     my $station = $obj->get_node_by_name($station_name);
     my $route = $obj->get_shortest_route($from, $to);
     my $metro_name = $obj->name;
     my $xml_file = $obj->xml;

EXAMPLE1
     # Pragmas.
     use strict;
     use warnings;

     # Modules.
     use Encode qw(decode_utf8 encode_utf8);
     use Map::Tube::Vienna;

     # Object.
     my $obj = Map::Tube::Vienna->new;

     # Get route.
     my $route = $obj->get_shortest_route(decode_utf8('Taborstraße'), decode_utf8('Kaisermühlen'));

     # Print out type.
     print "Route: ".encode_utf8($route)."\n";

     # Output:
     # Route: Taborstraße (U-Bahn-Linie U2), Praterstern (U-Bahn-Linie U1,U-Bahn-Linie U2), Vorgartenstraße (U-Bahn-Linie U1), Donauinsel (U-Bahn-Linie U1), Kaisermühlen (U-Bahn-Linie U1)

     # Get XML file.
     my $xml_file = $obj->xml;

     # Print out XML file.
     print "XML file: $xml_file\n";

     # GraphViz object.
     my $g = Map::Tube::GraphViz->new(
             'callback_node' => \&node_color_without_label,
             'driver' => 'neato',
             'tube' => $obj,
     ); 

     # Get graph to file.
     $g->graph('Vienna.png');

     # Print file.
     system "ls -l Vienna.png";
