title: Disable pre-populated file info comments in Xcode
body: <p>As a beginner, this is of no use to me:</p>
  
  <pre><code>//
  //  CarArrayController.m
  //  CarLot
  //
  //  Created by X on 22/03/13.
  //  Copyright (c) 2013 __MyCompanyName__. All rights reserved.
  //
  </code></pre>
  
  <p>It takes up unnecessary screen space. The first thing I do after creating a class is delete these lines manually. Is there a way to save me from this trouble?</p>
