 *
 * @code
 *
 * // Create a contact item in the root collection
 *
 * KABC::Addressee addr;
 * addr.setNameFromString( "Joe Jr. Miller" );
 *
 * Akonadi::Item item;

 * item.setPayload<KABC::Addressee>( addr );

 * Akonadi::ItemCreateJob *job = new Akonadi::ItemCreateJob( item, collection );
 * connect( job, SIGNAL(result(KJob*)), SLOT(jobFinished(KJob*)) );
