This time we are doing something new here. We are calling a helper; a helper is a
class that contains methods that can be reused from blocks, templates, controllers,
and so on. In our case, we are creating a helper that will retrieve all available registry
types. Follow these steps:
1. Navigate to app/code/local/Mdg/Giftregistry/Helper.
2. Open the Data.php class.
