<p>Report by Exception node - only passes on data if it has changed.</p>
<p>The node can either block until the <code>msg.payload</code> is
different to the previous one - <b>rbe</b> mode. This works on numbers, strings, and simple objects.</p>
<p>Or it can block until the value changes by a specified amount - <b>deadband</b> mode.</p>
<p>In deadband mode the incoming payload must contain a parseable <i>number</i> and is
output only if greater than + or - the <i>band gap</i> away from a previous value.</p>
<p>Deadband also supports % - only sends if the input differs by more than x% of the original value.</p>
<p>It can also ignore outlier values - <b>narrowband</b> mode.</p>
<p>In narrowband mode the incoming payload is blocked if it is more than + or - the band gap
away from the previous value. Useful for ignoring outliers from a faulty sensor for example.</p>
<p>Both Deadband and Narrowband allow comparison against either the <i>previous valid output value</i>, thus
ignoring any values out of range; or the <i>previous input value</i>, which resets the set point, thus allowing
gradual drift (deadband), or a step change (narrowband).</p>
<p><b>Note:</b> This works on a per <code>msg.topic</code> basis. This means that a single rbe node can
handle multiple topics at the same time.</p>
