  How can I dynamically reference template file in volt template? <br />
  like this:  <br />
        &nbsp;&nbsp;&nbsp;&nbsp; <code>{% include variable %}</code>  <br />
        &nbsp;&nbsp;&nbsp;&nbsp; when variable equal <code>footer.volt</code>, theen the program will reference file with name's <code>footer.volt</code> <br />
         &nbsp;&nbsp;&nbsp;&nbsp;when variable equal <code>index.volt</code>, then the program will reference file with name's <code>index.volt</code>... <br /><br /></p>
