/**
* Provides a listing of preset 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.
