    /*
    * Example adds certain named Product Attribute fields to the product Edit screen ready for completion.
    * (Pre-requisite )
    * This saves the Shop Admin having to add them manually.
    *
    * Why might you want to do this instead of adding Custom fields? There's plenty of nice documentation on adding custom fields
    * for example: http://www.remicorson.com/mastering-woocommerce-products-custom-fields/
    *
    * Well a Product Attributes are a built in WooCommerce feature, using Terms which are a built in Wordpress feature.
    * - no add-ons required
    * - pre-existing functionality including
    * - ability to link from Product to archive page of products sharing the same term
    * - Term selection, hide or show Attribute, use for Product Variations
    * - built-in configuration screens, display and selection mechanisms
    * - highly compatible with plugin components for example to
    * - enhance Product Attributes display,
    * - show Variation swatches,
    * - translate Attributes and terms
    * - offers a level of separation between built-in fields and extension fields
    * (though custom fields can be added to their own tab, and some fields make sense to add to other tabs)
    *
