/*
The link/button text more specifically, are those which contain (non case sesitive) "Next", "Prev", "Previous";
or has ">"/"<" (and similar meaning characters); or "«"/"»". The ID and class names are also checked. "«"/"»" have lower priority over the rest conditions.

This script doesn't take into account of links whose contents is an image rather than text, or whose text is a CSS text contents.

If next/previous navigation link is specified in the HTML metadata, it will be used as a priority.
