/**
* The built-in pagination functions provide either two buttons (forward / back)
* or lots of buttons (forward, back, first, last and individual pages). This
* plug-in meets the two in the middle providing navigation controls for
* forward, back, first and last.
*
* DataTables has this ability built in using the `dt-string full` option of
* the `dt-init pagingType` initialisation option. As such, this plug-in is
* marked as deprecated.
*
* @name Four button navigation
* @summary Display forward, back, first and last buttons.
* @deprecated
* @author [Allan Jardine](http://sprymedia.co.uk)
*
* @example
* $(document).ready(function() {
* $('#example').dataTable( {
* "sPaginationType": "four_button"
* } );
* } );
