/**
* count_indexed.js
*
* Runs count on an indexed field (using hint), which results in an index scan,
* and verifies the result.
* Each thread picks a random 'modulus' in range [5, 10]
* and a random 'countPerNum' in range [50, 100]
* and then inserts 'modulus * countPerNum' documents. [250, 1000]
* Each thread inserts docs into a unique collection.
