EXAMPLE

 Example:
 A dedicated process is being used to perform an optimization algorithm
 on the strings.  Send a new string, s, to the process, while receiving an
 optimized string, r, from it.
 
 PGAContext *ctx;
 MPI_Comm    comm;
 MPI_Status  status;
 int  s, r;
 :
 PGASendReceiveIndividual(ctx, s, PGA_NEWPOP, 1, PGA_SR_STRINGTOMODIFY,
 r, PGA_NEWPOP, 1, PGA_SR_MODIFIEDSTRING,
 comm, &status);
