	<p>Provides a input node for http, tcp or udp sockets. Topic is optional. These are server like sockets.</p>
	<p>The TCP and UDP sockets produce a <i>BUFFER</i> object msg.payload and NOT a String. If you need a String then use .toString() on msg.payload in your next function block.</p>
	<p>TCP and UDP sockets also provide <b>msg.fromip</b> of the form ipaddress:port</p>
