  <!--In Heurist, relationships are stored in a single relationship record type and 
        different types of relationship are distinguished by the relationship type field (attribute) whose values 
        can be organised hierarchichally. In FAIMS, each type of relationship is a separate record type, organised 
        into three classes - bidirectional, container and hierarchy-->
