generic class RelationGraph from GraphDS
(GraphDS_Item as any;
GraphDS_Attribute as any)
---Purpose: This generic class describe a network (or graph) of
-- Relations between Entities. an Item can be associated
-- to the Entity and respectively an Attribute to the
-- Relation. This class can be compared to the
-- DirectedGraph of this package. But here the Relation
-- (compared to the Edge) can describe links between more
-- than two Entities. Each link can be described as
-- oriented or not. Nested classes permit to edit and
-- visit that structure. Interface of visiting tools are
-- done as iterators.
