title: Elegant way to structure models into subfolders without creating submodules
body: <p>I have numerous models in my app/models folder. I'd like to clean this folder up a little bit. Move models that belong to each other in subfolders. The problem is that by convention the model class is namespaced into an according module. </p>
  
  <p>E.g.</p>
  
  <p>app/models/blog/post.rb<br>
  app/models/blog/comment.rb<br>
  app/models/user.rb</p>
  
  <p>so that:</p>
  
  <p>app/models/blog/post.rb</p>
  
  <pre><code>class Post &lt; ActiveRecord
  end
  </code></pre>
  
  <p>and not</p>
  
  <pre><code>class Blog::Post &lt; ActiveRecord
  end
  </code></pre>
