An iOS-like toggle button. It connects to its parent's state.
```jsx
const [enabled, setEnabled] = React.useState(true);

const handleClick = () => setEnabled(prevState => !prevState);

<Toggle enabled={enabled} onClick={handleClick} />
```

Small size option:
```jsx
const [enabled, setEnabled] = React.useState(true);

const handleClick = () => setEnabled(prevState => !prevState);

<Toggle enabled={enabled} onClick={handleClick} size="sm" />
```
