title: How to teach PhpStorm generate fully qualified class name corresponded to project's structure and vice verse
body: <p>In my new company didn't use namespaces at all... so fully qualified class name corresponded to PSR-0.</p>
  
  <p>Here is an example. Project structure looks like this...</p>
  
  <pre>
  App
    |-Controller
             |-Guest        
                   |-Book.php
  </pre>
  
  <p>Inside of the <code>Book.php</code> class name should look like this...
  <br>
  <b>class Controller_Guest_Book.php</b></p>
  
  <p>Now I need to create full structure and file name manually</p>

  <p>What I did:</p>
  
  <ul>
  <li>A point to PhpStorm root folder of the project.</li>
  <li>PhpStorm solves only namespace's problem.</li>
  <li>It generates correct namespaces but unfortunately there is no need.</li>
  </ul>
  
  <p>Is there a way to generate full class name correspond to project's structure and vice verse? Generate project structure depending on full class name?</p>
