	<p>The meaning of this node is to interrupt/reactivate flow messages.<br/>
	Normally, passes the input messages to the output. If you send a payload with a specific topic (you can set it on the node properties), the node stops sending output messages.<br/>
	It can also save the last message received and play later. This is useful if you wish to restore previous state to, for example, a light actuator.<br/>
	Please see the <a href="https://github.com/Supergiovane/node-red-contrib-boolean-logic-ultimate" target="_blank">README</a> on github for examples.
	</p>
	<p>
	The node will stop output messages, if it receives a payload = false <b>from the specified topic</b>.<br/>
	The node will resume output messages, if it receives a payload = true <b>from the specified topic</b>.<br/>
	Other that that, as soon as you send payload = false <b>from the specified topic</b>, the node stores the last received payload internally
	The node will output the current stored message plus an added property <b>isReplay</b> = true, if it receives a <b>play</b> = true from the specified topic.<br/>
