# Attribute ordering
# Ensures one value is greater or lesser than another (set of) value(s).
# The special value of :now will automatically become Time.now (without needing a lambda).
# Always skips over nil values; use :presence to validate those.
# eg: validates :start_at, before: :finish_at
# validates :start_at, before: {value_of: :finish_at, if: ... }
# validates :finish_at, after: [:start_at, :now]
# validates :finish_at, after: {values_of: [:start_at, :now], if: ... }
