#taxon_preview(taxon, max = 5) ⇒ Object
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.)
