Constructor.

The child class should call this constructor from its own constructor to override the default $args.

$args array|string Optional

Array or string of arguments.

• pluralstring
  Plural value used for labels and the objects being listed.
  This affects things such as CSS class-names and nonces used in the list table, e.g. 'posts'.
• singularstring
  Singular label for an object being listed, e.g. 'post'.
  Default empty
• ajaxbool
  Whether the list table supports Ajax. This includes loading and sorting data, for example. If true, the class will call the _js_vars() method in the footer to provide variables to any scripts handling Ajax events. Default false.
• screenstring
  String containing the hook name used to determine the current screen. If left null, the current screen will be automatically set.
  Default null.

Default: array()

This sets default arguments and filters. Developers should override this, calling the parent constructor to provide values for singular and plural labels, as well as whether the class supports AJAX.
