* This feature plug-in for DataTables adds page length control links to the
* DataTable. The `dom` option can be used to insert the control using the `L`
* character option and it uses the `lengthMenu` options of DataTables to
* determine what to display.
*
* @example
* $('#myTable').DataTable( {
* dom: 'Lfrtip'
* } );
*
* @example
* $('#myTable').DataTable( {
* lengthMenu: [ [10, 25, 50, -1], [10, 25, 50, "All"] ]
* dom: 'Lfrtip'
* } );
