title: get Facebook Group Id using identifier or url
body: <p>I would like to get a facebook group id by using a URL or specific identifier.</p>
  
  <p>For ex: <strong><a href="http://www.facebook.com/groups/chennaifoodies/" rel="noreferrer">http://www.facebook.com/groups/chennaifoodies/</a></strong> should give group id 194462073956868.
  Is there way to get the group id by using above URL or identifiers like 'chennaifoodies'? </p>
  
  <p>If I tried <strong><a href="https://graph.facebook.com/chennaifoodies" rel="noreferrer">https://graph.facebook.com/chennaifoodies</a></strong>, then it gives the fan page id. </p>
  
  <p>I think 'wallflux' has done a wonderful script, so I need a script like that to get group the id. </p>
  
  <p>is there any way to get a group id using graph api or fql?</p>
  
  <p>Thanks.</p>
