A better require statement

I happen to come across a better `require` statement for project specific imports. 
This line goes into `app.js`: 

``` js
global.rootRequire = function (name) {
    return require(__dirname + '/' + name);
}
```

This is helpful if you find yourself deep in a folder:

```
var auth = require('../../../auth/auth.service');

var auth = rootRequire('auth/auth.service');
```

Any thoughts?
