 ### Some definitions
 
 * EndpointDescription Describes a remote service using service interfaces, remote url and all other properties to import the remote service.
 * EndpointListener a service that is to be notified when remote Endpoints described by OSGi filters appear or disappear.

 * Listens to local services and decides which to expose. It can also add properties to change the way services are exposed. 
   For the services to be exported it calls RemoteServiceAdmin.exportService to do the actual export. Then notifies EndpointListeners

 According to its role the TopologyManager of course does not directly implement the enhancements above. It simply creates the necessary
 calls to a suitable RemoteServiceAdmin.

 Is called by the Topology Manager to expose local services as remote endpoints and create local proxy services as clients for 
 remote endpoints.
