/**
 * Provides a listing of danse_moderation_notifications entities.
 *
 * List Controllers provide a list of entities in a tabular form. The base
 * class provides most of the rendering logic for us. The key functions
 * we need to override are buildHeader() and buildRow(). These control what
 * columns are displayed in the table, and how each row is displayed
 * respectively.
 *
 * Drupal locates the list controller by looking for the "list" entry under
 * "controllers" in our entity type's annotation. We define the path on which
 * the list may be accessed in our module's *.routing.yml file. The key entry
 * to look for is "_entity_list". In *.routing.yml, "_entity_list" specifies
 * an entity type ID. When a user navigates to the URL for that router item,
 * Drupal loads the annotation for that entity type. It looks for the "list"
 * entry under "controllers" for the class to load.
