-/**
- * Implements the M-N (many to many) relationship via association table.

- *
- * +---------+ +------------------+ +----------+
- * | Article | * -----> * | Article_Category | * <----- * | Category |
- * +---------+ +------------------+ +----------+
- *
- * Where one article may have 0 or more categories and each category may have 0
- * or more articles. We may model Article-Category object relationship
- * as active record as follows.
- *
- * class ArticleRecord
- * {
- * const TABLE='Article';
- * public $article_id;
- *
- * public $Categories=array(); //foreign object collection.
- *
- * public static $RELATIONS = array
- * (
- * 'Categories' => array(self::MANY_TO_MANY, 'CategoryRecord', 'Article_Category')
- * );
- *
- * public static function finder($className=__CLASS__)
- * {
- * return parent::finder($className);
- * }
- * }
- * class CategoryRecord

- *
- * public static function finder($className=__CLASS__)
- * {
- * return parent::finder($className);
- * }
- * }
- *
- *
- * The static $RELATIONS property of ArticleRecord defines that the
- * property $Categories has many CategoryRecords. Similar, the
- * static $RELATIONS property of CategoryRecord defines many ArticleRecords.
- *
- * The articles with categories list may be fetched as follows.
- *
- * $articles = TeamRecord::finder()->withCategories()->findAll();
- *
- * The method with_xxx() (where xxx is the relationship property
- * name, in this case, Categories) fetchs the corresponding CategoryRecords using
- * a second query (not by using a join). The with_xxx() accepts the same
- * arguments as other finder methods of TActiveRecord.
