* `next()`: return next integer random number [`-2147483648`...`2147483647`]
* `next(min, max)`: return next integer random number [`min`...`max`]
* `rand_normal_dist(min, max, num_trials=6)`: return normally distributed random number [`min`...`max`]
* This is only a rough approximation of a normal distribution with mean=(max-min)/2 and variance=1
* This is only a rough approximation of a normal distribution with:
* mean = (max - min) / 2, and
* variance = (((max - min + 1) ^ 2) - 1) / (12 * num_trials)
* Increasing num_trials improves accuracy of the approximation
