Note: for new implementations consider using IRegistryEventListener. 

A registry change listener is notified of changes to extensions points in the
registry.  These changes arise from subsequent manipulation of the registry after
it was initially created.

This interface can be used without OSGi running.

Clients may implement this interface.

Notifies this listener that some registry changes are happening, or have
already happened.

The supplied event gives details. This event object (and the deltas in it) is valid

to be called directly by clients.
