It couldn't hurt! I'm thinking of extending the `selectors` object defined below--something like:

```javascript
var elements = {
  scrollList: {
    selector: '#edit-alarm'
  },
  backButton: {
    selector: '#alarm-close'
    event: 'click'
  }
};
```

...which also makes me realize: there's no point in defining memoized getters on the prototype, since they are all immediately invoked by the constructor. We might as well skip the indirection and select the elements immediately within the constructor.
