/*
|

|
* 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.
