    Map::Tube::Prague - Interface to the Prague Metro Map.

SYNOPSIS
     use Map::Tube::Prague;

     my $obj = Map::Tube::Prague-&gt;new;
     my $routes_ar = $obj-&gt;get_all_routes($from, $to);

     my $line = $obj-&gt;get_line_by_name($line_name);
     my $lines_ar = $obj-&gt;get_lines;
     my $station = $obj-&gt;get_node_by_id($station_id);
     my $station = $obj-&gt;get_node_by_name($station_name);
