Other stuff that is GOOD: Collection classes

Ledgers say:

        'Stick::Role::HasCollection' => {
            item => 'consumer',
            collection_roles => [
                          'Moonpig::Role::Collection::ConsumerExtras',
                          'Stick::Role::Collection::Mutable',
                        ]
        },

This says that a ledger has a collection of consumer objects

        my $consumers = $ledger->consumer_collection

        my @consumers     = $consumers->all;
        my $n_consumers   = $consumers->count;
        my $some_consumer = $consumers->find_by_guid($guid);
        # etc.
