title: How to click on the angular-ui date picker popup Today button?
body: <p>I have been trying to fill in a form using Protractor of my Angular application. Only I am having trouble to click on the <code>Today</code>-button of the angular-ui calendar popup. </p>
  
  <p>I got it so far as clicking on it, but everything I tried I can't seem to be able to click on the Today button:</p>
  
  <pre><code>element(by.model('delivery.deliveryDate')).click();
  </code></pre>
  
  <p>Does anyone know how?</p>
