  <p>A node to control the Tinkerforge Dual Relay bricklet</p>
  <p>This node accepts a msg with payload containing a two
  element boolean array. The first value will set the state of
  the first relay and the second for the second array.</p>
  <p>Example:</p>
  <pre>{
  topic: 'foo',
  payload: [true,false]
  }</pre>
  <p>This will set the first relay closed and the second open.</p>
