RandomSeedGenerator (Apache Hadoop Rumen 3.4.1.300-dep-1001 API)

```
public class RandomSeedGenerator
extends java.lang.Object
```
The purpose of this class is to generate new random seeds from a master seed. This is needed to make the Random().next*() calls in rumen and mumak deterministic so that mumak simulations become deterministically replayable. In these tools we need many independent streams of random numbers, some of which are created dynamically. We seed these streams with the sub-seeds returned by RandomSeedGenerator. For a slightly more complicated approach to generating multiple streams of random numbers with better theoretical guarantees, see P. L'Ecuyer, R. Simard, E. J. Chen, and W. D. Kelton, ``An Objected-Oriented Random-Number Package with Many Long Streams and Substreams'', Operations Research, 50, 6 (2002), 1073--1075 http://www.iro.umontreal.ca/~lecuyer/papers.html http://www.iro.umontreal.ca/~lecuyer/myftp/streams00/
