NotifierDebug()

=s test
useful for debugging notification

=d
Responds to each packet by pushing it unchanged out its first output.  The
purpose of this element is that it provides a "signal" handler, which reports
the unparsed version of the appropriate notification signal.  If the element
is in a push context, this is the downstream full signal; if it's in a pull
context, this is the upstream empty signal.

=h signal r
Returns the unparsed version of the signal.
