Hjul

Hjul is a thin wrapper around mio-extra timers. Example usage:

```rust use hjul::Runner; use std::thread; use std::time::Duration;

let runner = Runner::new(Duration::from_millis(100), 100, 1024); let timer = runner.timer(|| println!("fired"));

timer.start(Duration::from_millis(200));

// wait for timer to fire thread::sleep(Duration::from_millis(500));

// start the timer again timer.start(Duration::from_millis(200));

// stop timer immediately timer.stop();

// start the timer again timer.start(Duration::from_millis(200));

// timer is stopped when it goes out of scope ```
