Detailed Description

A global service for random number generation.

The RandomGenerator class uses stateful logical-id based RNG streams. In order to ensure determinism, with this version of CNum's RNG implementation 2 threads cannot share an RNG associated with a logical id but can have their own RNGs associated with unique logical ids
