/**
* Very simple debugger that prints to the console (stdout) the sent and
* received stanzas. Use this debugger with caution since printing to the
* console is an expensive operation that may even block the thread since only
* one thread may print at a time.
*
*
* It is possible to not only print the raw sent and received stanzas but also
* the interpreted packets by Smack. By default interpreted packets won't be
* printed. To enable this feature just change the printInterpreted
* static variable to true.
