/**
 * Default controller handling i18n integration.
 *
 * Implements i18n string translation for all non-field properties marked as
 * 'translatable' and having the flag 'i18n string' set. This translation
 * approach fits in particular for translating configuration, i.e. exportable
 * entities.
 *
 * Requirements for the default controller:
 *  - The entity type providing module must be specified using the 'module' key
 *    in hook_entity_info().
 *  - An 'entity class' derived from the provided class 'Entity' must be used.
 *  - Properties must be declared as 'translatable' and the 'i18n string' flag
 *    must be set to TRUE using hook_entity_property_info().
 *  - i18n must be notified about changes manually by calling
 *    i18n_string_object_update(), i18n_string_object_remove() and
 *    i18n_string_update_context(). Ideally, this is done in a small integration
 *    module depending on the entity API and i18n_string. Look at the provided
 *    testing module "entity_test_i18n" for an example.
 *  - If the entity API admin UI is used, the "translate" tab will be
 *    automatically enabled and linked from the UI.
 *  - There are helpers for getting translated values which work regardless
 *    whether the i18n_string module is enabled, i.e. entity_i18n_string()
 *    and Entity::getTranslation().
 *
 *  Current limitations:
 *   - Translatable property values cannot be updated via the metadata wrapper,
 *     however reading works fine. See Entity::getTranslation().
