-/**
- * The "Categoryfinder" class takes a list of articles, creates an internal
- * representation of all their parent categories (as well as parents of
- * parents etc.). From this representation, it determines which of these
- * articles are in one or all of a given subset of categories.
- *
- * Example use :
- * <code>
- *     # Determines whether the article with the page_id 12345 is in both
- *     # "Category 1" and "Category 2" or their subcategories, respectively
- *
- *     $cf = new Categoryfinder;
- *     $cf->seed(
- *         array( 12345 ),
- *         array( 'Category 1', 'Category 2' ),
- *         'AND'
- *     );
- *     $a = $cf->run();
- *     print implode( ',' , $a );
- * </code>
