/**
* Interface for providing entity translation.
*
* Defines a set of methods to allow any entity to be processed by the entity
* translation UI.
*
* The entity translation UI relies on the entity info to provide its features.
* See the documentation of hook_entity_info() in the Entity API documentation
* for more details on all the entity info keys that may be defined.
*
* To make Entity Translation automatically support an entity type some keys
* may need to be defined, but none of them is required unless the entity path
* is different from ENTITY_TYPE/%ENTITY_TYPE (e.g. taxonomy/term/1), in which
* case at least the 'menu_base_path' key must be defined. This is used to
* determine the view and edit paths if they follow the standard path patterns.
* Otherwise the 'menu_view_path' and 'menu_edit_path' keys must be defined. If
* an entity type is enabled for translation and no menu path key is defined,
* the following defaults will be assumed:
* - menu_base_path: ENTITY_TYPE/%ENTITY_TYPE
* - menu_view_path: ENTITY_TYPE/%ENTITY_TYPE
* - menu_edit_path: ENTITY_TYPE/%ENTITY_TYPE/edit
* The menu base path is also used to reliably alter menu router information to
* provide the translation overview page for any entity.
* If the entity uses a menu loader different from %ENTITY_TYPE also the 'menu
* path wildcard' info key needs to be defined.
*
* Every entity type needs a translation controller to be translated. This can
* be specified through the 'translation_controller_class' key in the entity
* info. If an entity type is enabled for translation and no translation
* controller is defined, Drupal\translation_entity\EntityTranslationController
* will be assumed. Every translation controller class must implement
* Drupal\translation_entity\EntityTranslationControllerInterface.
*
* If the entity paths match the default patterns above and there is no need for
* an entity-specific translation controller class, Entity Translation will
* provide built-in support for the entity. It will still be required to enable
* translation for each translatable bundle.
*
* Additionally some more entity info keys can be defined to further customize
* the translation UI. The entity translation info is an associative array that
* has to match the following structure. Two nested arrays keyed respectively
* by the 'translation' key and the 'entity_translation' key: the first one is
* the key defined by the core entity system, while the second one registers
* Entity Tanslation as a field translation handler. Elements:
* - access callback: The access callback for the translation pages. Defaults to
* 'entity_translation_translate_access'.
* - access arguments: The access arguments for the translation pages. By
* default only the entity object is passed to the access callback.
*
* This is how entity info would look for a module defining a new translatable
* entity type:
* @code
* function mymodule_entity_info_alter(array &$info) {
* $info['myentity'] += array(
* 'menu_base_path' => 'mymodule/myentity/%my_entity_loader',
* 'menu_path_wildcard' => '%my_entity_loader',
* 'translation_controller_class' => 'Drupal\mymodule\MyEntityTranslationController',
* 'translation' => array(
* 'translation_entity' => array(
* 'access_callback' => 'mymodule_myentity_translate_access',
* 'access_arguments' => array(2),
* ),
* ),
* );
* }
* @endcode
*
* @see \Drupal\Core\Entity\EntityManager
