SYNOPSIS
     use Map::Tube::Samara;
     my $obj = Map::Tube::Samara->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;

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

             Get line object defined by name.
             Returns Map::Tube::Line object.

    "get_lines()"
             Get lines in metro map.
             Returns reference to unsorted array with Map::Tube::Line objects.

             Get shortest route between $from and $to node names. Node names in $from and $to are case insensitive.
             Returns Map::Tube::Route object.

    "get_stations($line)"
             Get list of stations for concrete metro line.
             Returns reference to array with Map::Tube::Node objects.
