107	This class encapsulates a set of MapReduce jobs and its dependency. It tracks
108	the states of the jobs by placing them into different tables according to their
109	states.
110
111	This class provides APIs for the client app to add a job to the group and to get
112	the jobs in the group in different states. When a
113	job is added, an ID unique to the group is assigned to the job.
114
115	This class has a thread that submits jobs when they become ready, monitors the
116	states of the running jobs, and updates the states of jobs based on the state changes
117	of their depending jobs states. The class provides APIs for suspending/resuming
118	the thread,and for stopping the thread.
