XXX THIS CLASS IS NEVER USED.

The abstract extension class that "real" extensions must subclass.

Node extensions augment the built-in services of the node with large components that are not readily transferred on a per capsule basis or are too specialized to be needed at all nodes within the network. (E.g., multicast extensions, RSVP, etc.)

I don't think any extensions have ever been written.
