module TaxonsHelper
# 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.)
