/**
 * @short Base class for all actions in the Akonadi storage.
 *
 * This class encapsulates a request to the pim storage service,
 * the code looks like
 *
 * @code
 *
 *  Akonadi::Job *job = new Akonadi::SomeJob( some parameter );
 *  connect( job, SIGNAL(result(KJob*)),
 *           this, SLOT(slotResult(KJob*)) );
 *
 * @endcode
 *
 * The job is queued for execution as soon as the event loop is entered
 * again.
 *
 * And the slotResult is usually at least:
 *
 * @code
 *
 *  if ( job->error() ) {
 *    // handle error...
 *  }
 *
 * @endcode
 *
 * With the synchronous interface the code looks like
 *
 * @code
 *   Akonadi::SomeJob *job = new Akonadi::SomeJob( some parameter );
 *   if ( !job->exec() ) {
 *     qDebug() << "Error:" << job->errorString();
 *   } else {
 *     // do something
 *   }
 * @endcode
 *
 * @warning Using the synchronous method is error prone, use this only
 *          if the asynchronous access is not possible. See the documentation of
 *          KJob::exec() for more details.
 *
 * Subclasses must reimplement doStart().
 *
 * @note KJob-derived objects delete itself, it is thus not possible
 * to create job objects on the stack!
