 * Here's what's happening with these hooks:
 * 1. WordPress detects theme in themes/sage
 * 2. When we activate, we tell WordPress that the theme is actually in themes/sage/templates
 * 3. When we call get_template_directory() or get_template_directory_uri(), we point it back to themes/sage
 *
 * We do this so that the Template Hierarchy will look in themes/sage/templates for core WordPress themes
 * But functions.php, style.css, and index.php are all still located in themes/sage
 *
 * themes/sage/index.php also contains some self-correcting code, just in case the template option gets reset
