title: featherlight.js trigger close from the iFrame
body: <p>I use featherlight to open a image upload/resize/cropping page via an iFrame.</p>
  
  <p>I would like to call the <code>closeTrigger</code> as soon as the user hits save (within the iFrame) so that they don't need to close it manually</p>
  
  <p>I'm a bit confused about this. I've checked the <code>min.js</code> but couldn't find anything, and I also didn't find the Javascript action tied to the closing button...</p>
  
  <p>Any ideas?</p>
