A seed is the value that is used by the random number generation algorithm to come up with new pseudo-random values.
pub type Seed
pub fn new(int: Int) -> Seed
Creates a new seed from a given integer.
pub fn random() -> Seed
Creates a new random seed. You can use it when you don’t care about having reproducible results and just need to get some values out of a generator using the random.step function.
