SYNOPSIS

 use Map::Tube::Moscow;
 my $obj = Map::Tube::Moscow->new;
 my $routes_ar = $obj->get_all_routes($from, $to);
 my $line = $obj->get_line_by_id($line_id);
 my $line = $obj->get_line_by_name($line_name);
 my $lines_ar = $obj->get_lines;
 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 $stations_ar = $obj->get_stations($line);
 my $metro_name = $obj->name;
 my $xml_file = $obj->xml;
