title: Sprockets can't find my js files in a folder
body: <p>I'm using the Asset Pipeline. I moved some of my JS into a "global" folder. Now sprockets can't find those files. Why? I'm using Ruby on Rails 4.</p>
  
  <pre><code>javscripts
  |-- global
  |   |-- someglobalstuff.js
  |   |-- moreglobalstuff.js
  |-- application.js
  |-- homePage.js
  |-- userPage.js
  </code></pre>
  
  <p>My application.js file has this:</p>
  
  <pre><code>//= require_tree .
  </code></pre>
