DESCRIPTION
    It currently provides functionality to find the shortest route between
    the two given nodes.

     my $line = $obj->get_line_by_name($line_name);

    Get line object defined by name.

    Returns Map::Tube::Line object.

  "get_lines"
     my $lines_ar = $obj->get_lines;

    Get lines in metro map.

    Returns reference to unsorted array with Map::Tube::Line objects.

EXAMPLE1
     use strict;
     use warnings;

     use Encode qw(decode_utf8 encode_utf8);
     use Map::Tube::Minsk;

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

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

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

     my $xml_file = $obj->xml;

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

     # Output like:
