title: Change date in pickadate.js
body: <p>So I'm using <a href="http://amsul.ca/pickadate.js/" rel="nofollow">http://amsul.ca/pickadate.js/</a> and I can't seem to figure out how to set a specific date into the date picker.
  (Date picker for pickadate.js v3.5.6, <a href="http://amsul.github.io/pickadate.js/date.htm" rel="nofollow">http://amsul.github.io/pickadate.js/date.htm</a>).</p>
  
  <p>For example if I say:</p>
  
  <pre><code>var today = '01-01-1983';
  picker.val(today);
  </code></pre>
  
  <p>This will change the text inside the input, but when you open the picker the date has not been set to 1983.</p>
  
  <p>So how do you use js/jquery to update the date in the date picker?</p>
