it was dictated by the external API, basically, we want to do this:

```
var l = new Locator();
app.set('locator', l);

/// more code here

l.parseBundle('path/to/parse');
```

we need multiple moving parts to rely on `app.get('locator')`, and they should know when locator is ready to be used, which is triggered by `parseBundle()`.

any thoughts around that?
