 * Here's what's happening with these hooks:

 * 2. Upon activation, we tell WordPress that the theme is actually in themes/sapwood/public/templates
 * 3. When we call get_template_directory() or get_template_directory_uri(), we point it back to themes/sapwood
 *
 * We do this so that the Template Hierarchy will look in themes/sapwood/public/templates for core WordPress themes
 * But functions.php, style.css, and index.php are all still located in themes/sapwood
 *
 * This is not compatible with the WordPress Customizer theme preview prior to theme activation
 *
