Hi, I want to use the module Clusterize, but I have problems when trying it. When I type the code: 

use Clusterize;
my $clusterize = Clusterize->new();
    
$clusterize->add_pair(1,['1', '2', '3' ]);
$clusterize->add_pair(2,['4', '6', '5']);
$clusterize->add_pair(3,['1', '2', '3', '2', '3']);
$clusterize->add_pair(4,['1', '2', '3' ]);
$clusterize->add_pair(5,['4', '6', '5']);
$clusterize->add_pair(6,['1', '2', '3', '2', '3']);
$clusterize->add_pair(7,['1', '2', '3' ]);
$clusterize->add_pair(8,['4', '6', '5']);
$clusterize->add_pair(9,['a', 'b', 'c', 'd', 't']);

my @clusters = $clusterize->list;
print scalar(@clusters);

The result is 0. So there is no element in the clusters array. Can anyone help me how to use this module?
