-----------------------------
Due Date: 10/Jun/11
Affects Version/s: 0.5
Fix Version/s: 0.6
Assignee: Sean Owen
Labels: random rng seed (was: )
I'm assigning to me to commit, after 0.5, changes for two aspects of this
discussion:
- RandomWrapper.setSeed() will now work, by instantiating a new RNG
- static Random variables will be made into instance variables where possible
> Random generator objects- slight refactor

> Problems:
> * The uncommons RepeatableRNG classes are the basis of RandomUtils.
> ** These classes cheerfully ignore setSeed.
> * Some people in the project want to move off Uncommons anyway.
> This patch uses the org.apache.commons.math.random.RandomGenerator classes
> instead of org.apache.uncommons.maths.RepeatableRNG classes.
