title: use "Class" as entity name in symfony2.1
body: <p>I have an entity which should logically be called a &quot;Class&quot; (as in a class in school)</p>
  <p>But when using</p>
  <pre><code>class Class {
  </code></pre>
  <p>in my code, it obviously throws an error.</p>
  <p>because I realize this is a reserved keyword, hence the &quot;obvious&quot;</p>
  <p>Is there any way around this besides giving the entity a different name?</p>
