class Card
  module Model
    # API to create and update cards.
    # It is intended as a helper for "external" scripts
    # (seeding, testing, migrating, etc) and not for internal application code.
    # The general pattern is:
    # All methods use the ActiveRecord !-methods that throw exceptions if
    # somethings fails.
    # All !-methods in this module rename existing cards
    # to resolve name conflicts)
