title: Google Calendar Javascript API listing ALL events from ALL calendars
body: <p>I can list a selected calendar events by adding the calendarID to the script:</p>
  
  <pre><code>   var request = gapi.client.calendar.events.list({ 
         'calendarId': 'primary'
      }); 
  </code></pre>
  
  <p>this gets the primary calendar  and by swopping out the 'primary' to the calendar id required </p>
  
  <pre><code>   'calendarId': '?????????????????@group.calendar.google.com'
  </code></pre>
  
  <p>But what I would like to do is list ALL events from ALL calendars, so is there away to do this like below for EG:</p>
  
  <pre><code>    'calendarId': 'ALL'
  </code></pre>
