Ensure Nested Presenters works

[heymichaelp]

This code should work:

var PersonPresenter = Presenter.extend({
  customAttributes: {
    fullName: function() {
      return this.attributes.firstName + ' ' + this.attributes.lastName;
    }
  }
})

var LawyerPresenter = PersonPresenter.extend({
  customAttributes: {
    fullNameEsq: function() {
      return this.customAttribute('fullName') + ', Esq.';
    }
  }
})

var person = {
  firstName: 'Michael'
, lastName: 'Phillips'
}

LawyerPresenter.present( person );
// returns { firstName: 'Michael', lastName: 'Phillips', fullName: 'Michael Phillips', fullNameEsq: 'Michael Phillips, Esq.' }
