# Defines sets of privileges

# To create a new set: PrivilegeSet.add :set_name, "Some comment on what this
# set does"
#
# To retrieve a privilegeset, use the sets attribute. This is a Hash containing
# PrivilegeSetRecords. Usage: PrivilegeSet.sets(:set_name). If the PrivilegeSet
# already exists, an ArgumentError is thrown stating the set was already
# defined.
