   @short A convenience class bundling together multiple DeleteJobs.

   To use a MultiDeleteJob, pass it a CryptoBackend implementation,

   connect the progress() and result() signals to suitable slots and

   then start the delete with a call to start(). This call might

   fail, in which case the MultiDeleteJob instance will have scheduled

   it's own destruction with a call to QObject::deleteLater().

   After result() is emitted, the MultiDeleteJob will schedule it's own

   destruction by calling QObject::deleteLater().
