DBIx::SearchBuilder::Unique - Ensure uniqueness of records in a collection

       Currently, DBIx::SearchBuilder makes exceptions for databases which cannot handle both "SELECT DISTINCT"
       and ordering in the same statement; it drops the "DISTINCT" requirement. This, of course, means that you
       can get the same row twice, which you might not want. If that's the case, use this module as a mix-in,
       and it will provide you with an "AddRecord" method which ensures that a record will not appear twice in
       the same search.
