+The counts (add referenced and unrefrenced) output by `cingest verify` should equal :

+```
+test.ci.bulk.map.task * test.ci.bulk.map.nodes * num_bulk_generate_jobs
+```

+Its possible the counts could be slightly smaller because of collisions. However collisions 
+are unlikely with the default settings given there are 63 bits of randomness in the row and 
+30 bits in the column.  This gives a total of 93 bits of randomness per key.
