Summary __repr__ tuple index out of range

[HJTP]

Hi,

The repr of the Summary class features a formatting string containing {0} up to {4}, whereas the tuple only provides four items. This results in an IndexEror.

    def __repr__(self):
        return 'Summary({0}, {1}, {2}, {3}, {4})'.format(
            repr(self.url), repr(self.article_html), repr(self.title), repr(self.summaries)
        )

Should be fixed.
