/**
 * Load the Genesis-fied templates, instead of the WooCommerce defaults.
 *
 * Hooked to 'template_include' filter
 *
 * This template loader determines which template file will be used for the requested page, and uses the
 * following hierarchy to find the template:
 * 1. First looks in the child theme's 'woocommerce' folder.
 * 2. If no template found, falls back to GCW's templates.
 *
 * For taxonomy templates, first looks in child theme's 'woocommerce' folder and searches for term specific template,
 * then taxonomy specific template, then taxonomy.php. If no template found, falls back to GCW's taxonomy.php.
 *
 * GCW provides three templates in the plugin's 'templates' directory:
 * - single-product.php
 * - archive-product.php
 * - taxonomy.php
 *
 * Users can override GCW templates by placing their own templates in their child theme's 'woocommerce' folder.
 * The 'woocommerce' folder must be a folder in the child theme's root directory, eg themes/my-child-theme/woocommerce
 * Permitted user templates (as per WP Template Hierarchy) are:
 * - single-product.php
 * - archive-product.php
 * - taxonomy-{taxonomy-name}-{term-name}.php
 * - taxonomy-{taxonomy-name}.php
 * - taxonomy.php
 *
 * Note that in the case of taxonomy templates, this function accommodates ALL taxonomies registered to the
 * 'product' custom post type. This means that it will cater for users' own custom taxonomies as well as WooC's.
 *
 * @since 0.9.0
 *
 * @param string $template Template file as per template hierarchy
 * @return string $template Specific GCW template if a product page (single or archive)
 * or a product taxonomy term, or returns original template
