title: Use Twig Custom Set Variables From an Include
body: <p>I'm trying to include a twig file with a bunch of custom set variables and then use the variables in the multiple other template files. Similar to how including a PHP file works. </p>
  
  <p>I don't seem to have access to the variables set inside the include in my index file. </p>
  
  <p>Is there any way to do this?</p>
  
  <p><b>Sample Code</b> *<em>Edited</em></p>
  
  <p>Included File:</p>
  
  <pre><code>{# variables.html #}
  {% set width = "100" %}
  {% set height = "250" %}
  </code></pre>
  
  <p>Template File:</p>
  
  <pre><code>{# index.html #} 
  {% include 'variables.html' %}
  {{ width }}
  {{ height }}
  </code></pre>
  
  <p>Expected Outcome:</p>
  
  <pre><code>100 250
  </code></pre>
  
  <p>Actual Outcome:</p>
  
  <pre><code>// Nothing gets output
  </code></pre>
