The documentation is missing info about how to enable LevelChangePropagator in a logback.groovy file.

I came up with this:

LevelChangePropagator levelChangePropagator = new LevelChangePropagator()
levelChangePropagator.setContext(context)
levelChangePropagator.start()
context.addListener(levelChangePropagator)

Is there a better/easier way I'm missing? Current approach is modeled after what the XML implementation is doing...
