Subject [jira] Updated: (NUTCH-240) Scoring API: extension point, scoring filters and an OPIC plugin

Andrzej Bialecki  updated NUTCH-240:

    Attachment: Generator.patch.txt

> This patch refactors all places where Nutch manipulates page scores, into a plugin-based

easier to understand how scoring works.
> Multiple scoring plugins can be run in sequence, in a manner similar to URLFilters.
> Included is also an OPICScoringFilter plugin, which contains the current implementation
of the scoring algorithm. Together with the scoring API it provides a fully backward-compatible
