| Root callback listener. The only thing the callback needs from
all listeners is that they be able to create a subscription.
Note that this could extend org.cougaar.planning.plugin.legacy.PluginDelegate, and
then we could get the subscribe method, but we would also get
all the other delegate methods, cluttering the interface.
However, if we find that we need listeners to have a lot of the
methods from PluginDelegate (e.g. publishAdd, publishChange),
then we might want to revisit this.
