Bundled Products - provide a way to find all Bundles that contain a given Product
Product Bundles are useful, but it's an incomplete solution. We need to be able to list all Bundles that contain a given Product. More specifically, on the single post view of a specific Product, we want to upsell the customer to one of the Bundles we offer that include the Product they're looking at. Bonus points if there is an EFFICIENT way to do this (other than running through all Products, checking if it is a Bundle, running through its components looking for a match, lather rinse repeat).
