/*
* This plug-in adds another pagination option similar to `full_numbers`, except
* it adds ellipses around the page numbers when applicable. You can set how
* many page numbers should be displayed with the iShowPages option.
*
* This plug- in extends the oStdClasses object with the following properties:
* sPageEllipsis, sPageNumber and sPageNumbers.
*
* It also extends the oSettings object with the following properties:
* _iShowPages, _iShowPagesHalf, _iCurrentPage, _iTotalPages, _iFirstPage and
* _iLastPage.
*
* Note that DataTables 1.10 has this ability built in. As such, this plug-ins
* has been marked as deprecated, but may still be useful for if you are using
* an old version of DataTables.
*
* @name Ellipses
* @summary Show ellipses in the pagination control where there is a gap in numbers
* @deprecated
* @author [Dave Kennedy](http://daveden.wordpress.com/)
* @example
* $(document).ready(function() {
* $('#example').dataTable({
* 'sPaginationType': 'ellipses'
* });
