Test:

properties of predefined distributions provided for convenience

• the upper bound for rani(bound) is exclusive
• uniform distributions are sufficiently uniform
• spread of normal distribution is within expected scale

Test:

demonstrate that random number sequences can be reproduced

• use a rigged SeedNucleus, always returning a fixed sees
• build two distinct random sequence generators, yet seeded from the same source; they will produce the same sequence
• sequences can be re-shuffled by a seed value, so that the following random numbers will start to differ
• but even this re-shuffling is deterministic
