/* Example */
$shoes = new Shoes();
$brand = ShoeBrands::model()->findByPk(1);

//Assuming Shoes contains two attributes called brand_id and brand_name
//The $shoes model will be returned with $brand->id set as $shoes->brand_id and $brand->name set as $shoes->brand_name
list($brand, $shoes) = mapModelToModel($brand, $shoes, array( 'brand_id'=>'id', 'brand_name'=>'name' ));

//This becomes very helpful when you are mapping large sets of (for example API) data to internal local tables.
