Packer is a GPL Cart module that tries to solve "4D" bin packing/knapsack problem. Useful when you need to know box size/weight to calculate shipping costs. Allows to automatically define the number of boxes needed to fit all the products while adding a new order (saved under $order['data']['packages']). Administrators can also check whether a list of products fits into a box. Based on the BoxPacker library.
