title: Best way to load module/class from lib folder in Rails 3?
body: <p>Since the latest Rails 3 release is not auto-loading modules and classes from lib anymore,
  what would be the best way to load them?</p>
  
  <p>From github:</p>
  
  <blockquote>
  <pre><code>A few changes were done in this commit:
  
  Do not autoload code in *lib* for applications (now you need to explicitly 
  require them). This makes an application behave closer to an engine 
  (code in lib is still autoloaded for plugins);
  </code></pre>
