/* Function:  write_MPI_master_loop(dfp,dpi,gm)
 *
 * Descrip:    The master mpi process loop.
 *
 *             The essential idea here is that there is a queue of processes waiting 
 *             for jobs; they indicate their readiness by sending a message to the master.
 *             The master then reads in the score (if necessary), and sends off a job to 
 *             the slave (if there are more jobs to be done).
 *
 *             Here is the pseudo code:
 *
 *             check number of processes, and allocate space for (n-1) datascore objects
 *
 *             initialize the databases
 *
 *             forever {
 *
 *               Receive a message
 *               if the message contains data
 *                 process it
 *
 *               if there are no more jobs to be done
 *                 send a message to the slave, telling it to die
 *
 *               if all the slaves have been notified
 *                 Terminate MPI and return.
 *
 *               if we have not done everything
 *                 Pack data, and dispatch; do bookkeeping, reload next target
 *             }
 *
