=head2 Class Methods
=head3 get_usage_count
$count = Koha::Authorities->get_usage_count({ authid => $i });
Returns the number of linked biblio records.
Note: Code originates from C4::AuthoritiesMarc::CountUsage.
This is a class method, since the authid may refer to a deleted record.

=head3 linked_biblionumbers
my @biblios = Koha::Authorities->linked_biblionumbers({
authid => $id, [ max_results => $max ], [ offset => $offset ],
});
Returns array of biblionumbers, as extracted from the result records of
the search engine.
This is a class method, since the authid may refer to a deleted record.
