    <p>A function that encodes lat,lon to and from a geohash.</p>
    <p>If the <b>msg.payload</b> is a string it tries to see if it's a geohash -
    if so it tries to decode it and outputs a payload object containing
    <ul><li>latitude<li>longitude<li>error.latitude<li>error.longitude</ul></p>
    <p>If the <b>msg.payload</b> is an object with properties lat or latitude and lon or longitude
    - it will add a <b>geohash</b> property to the payload.</p>
    <p>The precision can be set by <b>msg.payload.precision</b> from 1 to 9.
    <p><b>Note:</b> If the msg contains a .location property it will operate on that in preference to the .payload.</p>
