2 for each loops that matches a a course that needs to have a book.

Description.MD

This logic matches a book with a course. This PHP logic is installed on the checkout page and it fires in notice if the user doesn't have the book that goes with the course. I think that it's bloated maybe somebody else can help me but as it is right now i t works fine but it's just fine.
