<p>A simple node to provide various functions across several previous values, including max, min, mean, high and low pass filters.</p>

<p>Messages arriving with different <code>msg.topic</code> can be treated as separate streams if so configured.</p>

<p>Max, Min and Mean work over a specified number of previous values.</p>

<p>The High and Low pass filters use a smoothing factor. The higher the number the more the smoothing. E.g. a value of 10 is

similar to an α of 0.1. It is analagous to an RC time constant - but there is no time component to this as the
