Another thing to keep in mind is that you can access all your models
through their relations.
so $this->model->relatedModel->anotherRelatedModel->find('all')
will work. Cake will build all the related models for the models in
$uses, so you can access them through relations if you don't need them
at $this->model.
Personally, I find uses most useful for loading models that would be
inaccessible with relations.
