commit 59ab70d300ca1221cb6512faf698be8c1c68b163
Author: aherbert <aherb...@apache.org>
AuthorDate: Wed Feb 27 14:24:55 2019 +0000
ConstructionPerformance: added generation of numbers after construction.
No RNG is constructed without using it so the benchmark now exercises
the RNG. Also added a method to construct using a long seed.
