 use MOBY::Adaptor::moby::queryapi::mysql  # implements this interface def
 my $m = MOBY::Adaptor::moby::queryapi::mysql->new(
    username => 'user',
    password => 'pass',
    dbname => 'mobycentral',
    port => '3306',
    sourcetype => 'DBD::mysql');
 my $objectid = $m->insert_object(

                The structure of the result hash is a bit complex because it is specifically
                designed for usage by MOBY::OntolgyServer::Relationships
                The result hash contains the entire table ${ontology}_term2term in order to

                $id_list    => Reference to array of Integers representing ${ontology}_ids
 Returns   :    reference to hash with the following structure:
                $resultHash->{Integer ${ontology}_id}->{String field_name} = field_value
 Notes     :    This function is generic with respect to which details (fields) are retrieved, but
                is restricted to those tables whose name is identical to the ontology name (i.e.
                currently 'object', 'service', 'namespace' and 'relationship')
                Makes use of the 'select ... from ... where ... in (<LIST>)' statement syntax
                in order to reduce the number of DB interactions
                Used in MOBY::OntologyServer::Relationships, but maybe useful for other purposes...
