# Determine Required items
#
# Each Package is aware of a list of ItemCategories that make sense for that Package.
# This list is called the Packages "Configuration". Within the configuration,
# the Package may identify certain categories that are required, meaning you must include
# an ItemPrice from that category in any order you make against that Package
