// just pass in the attribute and the attribute slug
// and the return value is the attribute's name

// example : (assuming attribute size has the option of "Extra Small" withe the slug of "extra-small")
// echo attribute_slug_to_title('attribute_pa_size', 'extra-small');
// returns
// "Extra Small"
