This returns the critical path cost.

    my $g = Graph->new(directed => 1);
    $g->add_weighted_vertex('Node1', 1);
    $g->add_weighted_vertex('Node2', 2);
    $g->add_edge('Node1','Node2');
    $g->add_weighted_vertex('Node3', 0.5);
    $g->add_edge('Node1','Node3');
    
    my $cp = Algorithm::CriticalPath->new( {graph => $g} );
    my $cost = $cp->cost();
