25513	Refactor the admin paginator customizations to make them reuseable	Vlada Macek	Nick Pope	"For large page counts I miss a standard way to display only interesting blocks of page links in the paginator. I guess Django should include one.

What do you think about integrating my implementation to {{{django.core.paginator.Page}}} drafted below?
**Template example at the bottom.**

{{{#!python
from django.core.paginator import Paginator, Page

class EllipsisPaginator(Paginator):
    def __init__(self, *args, **kwargs):
        # number of page links to always display after the first page
        self.start_wing = kwargs.pop('start_wing', 1)
        # number of page links to always display around the current page
        self.island_wings = kwargs.pop('island_wings', 2)
        # number of page links to always display before the last page
        self.end_wing = kwargs.pop('end_wing', 1)

        super(EllipsisPaginator, self).__init__(*args, **kwargs)

    def _get_page(self, *args, **kwargs):
        return EllipsisPage(*args, **kwargs)
