A signal is a structure that can yield an infinite amount of data. The API is very similar to `std::iter::Iterator` but with the assumption that it will never end.

# Example


```rust
use signal;

let my_signal = signal::square( signal::constant(0.25) );

loop {
    assert_eq!(my_signal.next(), 1.0);
    assert_eq!(my_signal.next(), 1.0);
    assert_eq!(my_signal.next(), -1.0);
    assert_eq!(my_signal.next(), -1.0);
}
```
