title: FB.logout() only from the application using javaScript SDK
body: <p>I get a user's data using the Facebook JavaScript SDK like this:</p>
  
  <pre><code>FB.login(function(response){
      // some code here
      userid = response.authResponse.userId;
  });
  </code></pre>
  
  <p>If the user id is odd (undesired one), then I call:</p>
  
  <pre><code>FB.logout();
  </code></pre>
  
  <p>This will make the user logout from my application and their Facebook account as well.</p>
  
  <p>I want it to only log out the user out from my application. They should not be logged out from their Facebook account.</p>
  
  <p>Below is the code I use to initialize the FB variable:</p>
  
  <pre><code>FB.init({appId: 'XXXXXXXXXXXXX', cookie: true, status: true, xfbml : true});
  </code></pre>
  
  <p>If a user logs in to my application then I get the response. The response has the status, access_token and user_id.</p>
  
  <p>Which variable should I use to achieve only logging them out of my application and not Facebook?</p>
