# Examples:
#
# product.touch # updates updated_at/on
# product.touch(:designed_at) # updates the designed_at attribute and updated_at/on
#
# If used along with +belongs_to+ then +touch+ will invoke +touch+ method on associated object.

# Brake.belongs_to :car, :touch => true
# Car.belongs_to :corporation, :touch => true
# @brake.touch #=> will also invoke @brake.car.touch and @brake.car.corporation.touch
