Gets a ``RelationshipList`` corresponding between the given peer ``Ids`` and relationship genus ``Type.

        Relationships`` of any genus derived from the given genus are
        returned.

        In plenary mode, the returned list contains all of the
        relationships corresponding to the given peer or an error
        results if a relationship is inaccessible. Otherwise,
        inaccessible ``Relationships`` may be omitted from the list.

        In effective mode, relationships are returned that are currently
        effective. In any effective mode, effective relationships and
        those currently expired are returned.

        arg:    source_id (osid.id.Id): a peer ``Id``
        arg:    destination_id (osid.id.Id): a related peer ``Id``
        arg:    relationship_genus_type (osid.type.Type): a relationship
                genus type
        return: (osid.relationship.RelationshipList) - the relationships
        raise:  NullArgument - ``source_id, destination_id,`` or
                ``relationship_genus_type`` is ``null``
