module Mobility
  module Plugins
=begin

Adds translated attribute names and values to the hash returned by #attributes.
Also adds a method #translated_attributes with names and values of translated
attributes only.

@note Adding translated attributes to +attributes+ can have unexpected
  consequences, since these attributes do not have corresponding columns in the
  model table. Using this plugin may lead to conflicts with other gems.
