/**
+ * 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.
