POE::Filter::JSON::Incr::Error - Input error marker

	# enable the creation of error objects
	POE::Filter::JSON::Incr->new(
		errors => 1,
	);

	# and in your event handler, check for them:
	if ( blessed($_[ARG0]) and $_[ARG0]->isa("POE::Filter::JSON::Incr::Error") ) {
		warn "input error: " . $_[ARG0]->error;
	} else {
		# $_[ARG0] is JSON data
	}

This is just a simple container for errors and the chunk of text that created the error.
