title: Where can I initialize module-wide variables?
body: <p>I'm trying to do something like this:</p>
  
  <pre><code>angular.module('MyModule', ['ui'])
      .config(function($rootScope) {
          $rootScope.Gender = {
              'M': 'Male',
              'F': 'Female',
              'U': 'Unknown',
          };
      })
  </code></pre>
  
  <p>But I get this error:</p>
  
  <blockquote>
    <p>Uncaught Error: Unknown provider: $rootScope from MyModule</p>
  </blockquote>
  
  <p>If I can't access <code>$rootScope</code> inside my module config, where's the proper place to initialize module-wide variables?</p>
