	<p>A node to give the suns relative position for a given location.</p>
  <p><strong>Inputs:</strong></p>
  <ul>
    <li>Latitude: The Latitude of the location you are interested in.</li>
    <li>Longditude: The Longditude of the location you are interested in.</li>
    <li>Period: Time in minutes to output data (defaults to 5mins).</li>
  </ul>
  <p><strong>Outputs:</strong></p>
  <pre>{
  "azimuth": 0.36900883056765676, 
  "altitude": 0.36796818774968365, 
  "percent": 89.8566247170534 
}</pre>
  <p>Where:</p>
  <ul>
    <li>azimuth: The position of the Sun in radians  (direction along the 
horizon, measured from south to west), e.g. 0 is south and Math.PI * 3/4 is 
northwest.</li>
    <li>altitude: The hight of the Sun above the horizon in radians. Where 0 is 
at the horizon and PI/2 is directly overhead.</li>
    <li>percent: How close the Sun is to it's highest position of the day, so 0%
is at sun rise and 100% will be the highest point the sun reaches for the 
given position and day.</li>
  </ul>
