domain_nodeapi(&$node, $op, $a3 = NULL, $a4 = NULL)

Implement hook_nodeapi().

This function is used to provide debugging information and to prep values from the {domain_access} table when editing nodes. Since not all users can see the domain access editing checkboxes, we pass some node_access values as hidden elements.
