Code review

This is a fake PR in an attempt to do a helpful code review of this.
Again using `.map` here would be much better. Use `.each` as a last resort there are better ways to loop over objects. See [underscore#collections](http://underscorejs.org/#collections) for examples.
This could be `this.collection.map(function (row) { return JSON.stringify(row.toJSON(), null, 5); });`
