A generic, low-overhead rate counter for frames-per-second indicators,
measurement averaging, and more.

```rust
use update_rate::{RateCounter, RollingRateCounter};

let mut c = RollingRateCounter::new(10);

loop {
    c.update();
    mycrate.work(); // Perform the slow operation
    println!("Updating at {}", c); 
}
```
