	 * )
	 *
	 * Using this mechanism you can build your own 'preloader' with tiny function
	 * snippets (and those can be re-used and shared online of course).

	 *    'b'       => 'review'    //define B as review
	 *    'matcher' => function( $a, $b ) {
	 *       return ( $b->movie_id == $a->id );  //Perform action if review.movie_id equals movie.id
	 *    }
	 *    'do'      => function( $a, $b ) {

	 * set a different SQL template (sprintf-style) for processing the original query.
	 *
	 * @note the SQL query provided IS NOT THE ONE used internally by this function,
	 * this function will pre-process the query to get all the data required to find the beans.
	 *
	 * @note if you use the 'book.*' notation make SURE you're
