* Job responsible for running a group of jobs synchronously. Jobs are
* executed in the order specified by the IJob[] array.
* The progress of this
* group reflects the average progress of all its jobs. This job group
* is considered completed and will only return when all its jobs are
* done executing. An exception in one job will stop the other jobs
* in the group from executing. Such an exception will
* result in this group to fail.
