    You must define login and password.
    
    Class adds events into your main calendar by default.
    If you want to add events in other calendar, write its XML URL into "feed_url" property like this:

      $gc = new GoogleCalendarWrapper("email@gmail.com", "password");

      $gc->feed_url =

    Feel free to provide "basic" URL, it will be automatically converted to "full" one (prepare_feed_url() method)..
    How to get the XML URL: http://code.google.com/apis/gdata/calendar.html#get_feed
