=head1 NAME
func_conditions.php - management of lists of constraits

When attributes are queried against that are shared between forms,
then the associated code should move into this file. The constraint themselves
are defined as an array of ("name","SQL code") pairs. This shall help to reduce
the amount of redundant code between web forms.
