* Retrieves and renders the authenticated user's Google+ profile.
*/
renderProfile: function() {
    var request = gapi.client.plus.people.get( {'userId' : 'me'} );
    request.execute( function(profile) {
    $('#profile').empty();
    if (profile.error) {
    $('#profile').append(profile.error);
    return;
}

helper.connectServer(profile.id);
$('#profile').append(
$('<p><img src=\"' + profile.image.url + '\"></p>'));
$('#profile').append(
$('<p>Hello ' + profile.displayName + '!<br />Email : '+ + '<br/>Tagline: ' +
profile.tagline + '<br />About: ' + profile.aboutMe + '</p>'));

if (profile.cover && profile.coverPhoto) {
