Usage

You can explicitly create a RouletteWheel<T> with new():

use roulette_wheel::RouletteWheel;

let rw: RouletteWheel<u8> = RouletteWheel::new();

You can push values in the roulette-wheel (which will grow the wheel as needed): ``` use roulette_wheel::RouletteWheel;

let mut rw = RouletteWheel::new();

rw.push(5., 'a'); rw.push(1., 'b');

// .iter() will not consume the roulette wheel for (fit, &ind) in rw.iter() { // do things with individuals here }

// .into_iter() consume the roulette wheel for (fit, ind) in rw.into_iter() { // do things with individuals here }
