Map::Tube::Minsk - Interface to the Minsk Metro Map.
SYNOPSIS
use Map::Tube::Minsk;
my $obj = Map::Tube::Minsk->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.

METHODS
new
my $obj = Map::Tube::Minsk->new;
Constructor.
Returns instance of object.
get_all_routes
[EXPERIMENTAL]
my $routes_ar = $obj->get_all_routes($from, $to);
Get all routes from station to station.
Returns reference to array with Map::Tube::Route objects.
get_line_by_id
my $line = $obj->get_line_by_id($line_id);
Get line object defined by id.
Returns Map::Tube::Line object.
get_line_by_name
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;

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";
# Output:
# Route: Уручча (Маскоўская лінія), Барысаўскі тракт (Маскоўская лінія), Усход (Маскоўская лінія)
EXAMPLE2

my $xml_file = $obj->xml;
# Print out XML file.
print "XML file: $xml_file\n";
# Output like:
# XML file: .*/minsk-map.xml

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