# I wrote this as a method for formatting group numbers to go into a pdf holiday voucher..
# its messy but it works..
# 
# Results:
# X adult(s), Y child(ren) and Z infant(s)
#
# rules: - 
# - pluralization hacks in case of 1 of each of them.
# - only show children and infants if they're > 0
# - at least one adult is always present
#
# examples...
# 
# 5 adults, 2 children and 1 infant
# 1 adult and 2 infants
# 2 adults and 1 child
# 1 adult
