/**
 * A simple Handler which logs the request and response messages to either the
 * console or a specified file (default "axis.log").
 * 
 * To use this, deploy it either in both the request and response flows (global,
 * service, or transport) or in just the response flow. If deployed in both
 * places, you'll also get an elapsed time indication, which can be handy for
 * debugging.
