    <p>Adds a slider widget to the user interface.</p>
	<p>The user can change its value between the limits (<b>min</b> and <b>max</b>). Each value change
    will generate a message with the value set as <b>payload</b>.</p>
    <p>If a <b>Topic</b> is specified, it will be added as <code>msg.topic</code>.</p>
    <p>Input messages will be converted to a number. The <b>min</b> value will be used if conversion fails,
    and it will update the user interface. If the value changes, it will also be passed to the output.</p>
    <p>The label can also be set by a message property by setting
    the field to the name of the property, for example <code>{{msg.topic}}</code>.</p>
    <p>Setting <code>msg.enabled</code> to <code>false</code> will disable the slider output.</p>
    <p>Note: An input msg to the slider node will not change the status information displayed unless the slider
    node output is connected to another node.</p>
