Random number generator based on the Math.random() builtin, which

available everywhere. This generator cannot be seeded.
Generate a single random number on the interval [0, 1],
updating whatever internal state the generator uses.
Returns number
setSeed
setSeed(seed: any): void
Set the seed of the generator; most generators should support
