 ## Usage
 The gem defines ``human_attribute_value`` as instance and class method on ``ActiveRecord::Base`` and ``ActiveModel::Model``.
 To translate a value it uses the I18n API. The translations are looked up from the current locale file under the key ``'activerecord.values.model_name.attribute_name.value'`` respectively ``'activemodel.values.model_name.attribute_name.value'`` by default.
