title: How to work with wordpress theme Customize API while using timber/twig
body: <p>I am using timber/twig to create wordpress themes, and I want the users to have the ability to select header images from the Theme Customize menu. So I used the Wordpress Customization API. 
  <a href="https://codex.wordpress.org/Theme_Customization_API" rel="nofollow noreferrer">https://codex.wordpress.org/Theme_Customization_API</a></p>
  
  <p>However, it seems timber/twig having some conflicts with the API. The theme sections did not show up in the menu while I am using timber, but the exactly code would work in a generic WordPress theme.</p>
  
  <p>I am not quite sure where to start? Am I missing anything?</p>
