title: Act as Votable - List who voted
body: <p>I've been using the <a href="https://github.com/ryanto/acts_as_votable" rel="nofollow">act as votable gem</a> and so far it's been working great. </p>
  
  <p>However I'm wondering if there's a way to create a list of who voted on the votable item? Say I have a blog post that users can vote on. I'd like to be able to click on the number of favorites and get a list of all voters who voted up on the post.</p>
  
  <p>I thought about creating another table with a blog post reference ID and a user ID, and adding an entry to that table every time the like method was called. But I was hoping there would be an easier way to accomplish this with the gem.</p>
