The CtlRelation class is the MBean class in the scenario description that allows
the user to disable device cards and update the routing table in a single step. It
extends the RelationSupport class in order to provide an implementation for the
RelationSupportMBean interface extended by the CtlRelationMBean interface. The
RelationSupport methods provide a mechanism for the relation service to vali-
date this external relation against its relation type.
