=head1 NAME

SL::DB::Manager::Chart - Manager class for the model for the C<chart> table

=head1 FUNCTIONS

=over 4

=item C<link_filter $link>

Returns a query builder filter that matches charts whose 'C<link>'
field contains C<$link>. Matching is done so that the exact value of
C<$link> matches but not if C<$link> is only a substring of a
match. Therefore C<$link = 'AR'> will match the column content 'C<AR>'
or 'C<AR_paid:AR>' but not 'C<AR_amount>'.
