title: include file without swig parsing it as a template
body: <p>I would like to include a file in a swig template without swig parsing it as a swig template. Something like raw tag for files.</p>
  
  <p>Using <a href="https://github.com/mrgamer/swig-highlight" rel="nofollow">swig-highlight</a> I would like to get this working.</p>
  
  <pre><code>{% highlight 'html' %}
      {% import 'some-template-file.html' %}
  {% endhighlight %}
  </code></pre>
  
  <p>Problem is 'some-template-file.html' is a Jekyll template and throws errors in swig.</p>
