/*
 * 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/
