Specifies some basic component interfaces to control components. These control interfaces can be provided by components that are able to control the corresponding "aspects". For example, a component which can migrate itself can provide the {@link org.etsi.uri.gcm.api.control.MigrationController MigrationController} interface, a component that can control its multicast bindings can provide the {@link org.etsi.uri.gcm.api.control.MulticastController MulticastController} interface, and so on.
