title: circledByCount returns NULL (Google+ API)
body: <p>I need to find out number of people who circled my Google+ account using Google API+.
  Well, currently my Google+ account is circled by 84 peoples.</p>
  
  <p>I tried using this people->get API to retrieve my profile.
  <a href="https://developers.google.com/+/api/latest/people/get" rel="nofollow">https://developers.google.com/+/api/latest/people/get</a></p>
  
  <p>All data are fine except this "circledByCount". It just returns NULL.</p>
  
  <p>Does it require special permission to show up?
  Btw, I'm using "login" and "email" scope to retrieve the data.</p>
  
  <p>Thanks</p>
