This should be exposed, so people can do this in their app.js:

```
app.get('/foo', mojito.dispatch('foo.index'));
```

which is going to be equivalent to do this in routes.json:

```
{
    "foo.index": {
         "path": "/foo",
         "verb": ["get"],
         "call": "foo.index"
    }
}
```

which also means, you will be able to do this in your templates: `{{#linkTo "foo.index"}}`, although this is not part of this PR, but the next one.
