title: Get LIKED youtube videos via API
body: <p>I know how to get the count of 'liked' videos using the YouTube API, but I want to get a list of those videos.</p>
  <p>After reading the docs, I think it can be done by getting the 'liked' playlist, but I do not know exactly how.</p>
  <p>Can I get the 'liked' video list through the Javascript API?</p>
