public function TMGMTJob::defaultLabel in Translation Management Tool 7

Defines the entity label if the 'entity_class_label' callback is used.

Specify 'entity_class_label' as 'label callback' in hook_entity_info() to let the entity label point to this method. Override this in order to implement a custom default label.
