module ActsAsHashable
  # This class serves as a singleton that can make mapped acts_as_hashable components.
  # It is important to note that these components *must* be acts_as_hashable objects.
  # In order to use you just have to subclass this class and implement
  # a method called 'registry', such as:
  #   def registry
  #     {
  #       'Table': Table,
  #       'Text': Text
  #     }
  #   end
  # You can also use the 'register' DSL:
  #   register 'some_class_name', SomeClassName
  #   register 'some_class_name', '', SomeClassName
  # or:
  #   register 'some_class_name', ->(_key) { SomeClassName }
