title: Get all contacts from a group in gmail
body: <p>I have several groups in my gmail account and I want to get for each group the assigned contacts. to get the groups, I use the following code:</p>
  
  <pre><code>        RequestSettings rs = new RequestSettings("TEST", "user@gmail.com", "password");
          // AutoPaging results in automatic paging in order to retrieve all contacts
          rs.AutoPaging = true;
          ContactsRequest cr = new ContactsRequest(rs);
  
          Feed&lt;Group&gt; fg = cr.GetGroups();
  </code></pre>
  
  <p>now I want to get the assigned contacts (for example group "Friends"), but I have no idea how to get them? any suggestions?</p>
