title: Adding a new config file in Laravel 5 not working
body: <p>I want a new config file in my Laravel 5 app to store all my constants in. After looking around the net I found the recommended solution seems to be to create a new config file that returns an array of key value pairs and then use that. So I created the following file:</p>
  
  <pre><code>&lt;?php
  // config/constants.php
  
  return [
      'SITE_NAME' =&gt; 'Site Name',
      'SITE_EMAIL' =&gt; 'email@site.com',
      'ADMIN_EMAIL' =&gt; 'admin@site.com'
  ];
  </code></pre>
  
  <p>Then in one of my controllers I try to access one of these values like so:</p>
  
  <pre><code>echo Config::get('constants.ADMIN_EMAIL');
  </code></pre>
  
  <p>I just get the following error:</p>
  
  <pre><code>FatalErrorException in WelcomeController.php line 46:
  Class 'App\Http\Controllers\Config' not found
  </code></pre>
  
  <p>Do I have to do something else to get it to work?</p>
