    # Retrieves the collection of products to display when "previewing" a taxon.  This is abstracted into a helper so
    # that we can use configurations as well as make it easier for end users to override this determination.  One idea is
    # to show the most popular products for a particular taxon (that is an exercise left to the developer.)

        TaxonsHelper is deprecated and will be removed in Harpiya 5.0.
        Please remove any `helper 'harpiya/taxons'` from your controllers.
