title: Default sort for doctrine model with annotations
body: <p>In question at <a href="https://stackoverflow.com/questions/4810868/default-sort-attribute-for-doctrine-model">Default sort attribute for Doctrine Model</a> a <code>.yml</code> is suggested to define a default sorting for a collection-valued association.</p>
  
  <p>I would like to have my models fetched by a default sorting, like following:</p>
  
  <pre><code>Foo:
      columns:
      ...
      options:
          orderBy: bar DESC
  </code></pre>
  
  <p>What is the annotation equivalent of this YAML-based setup?</p>
