Part 1: Input is a list of ingredients of the form:
Frosting: capacity 4, durability -2, flavor 0, texture 0, calories 5
Candy: capacity 0, durability 5, flavor -1, texture 0, calories 8
A recipe score is a product of the positive quantity scores (ignoring calories), where each quantity score is the product of the quantity and that product for each product.
For example, 4 Frosting and 2 Candy above, would have a score of of -2 * 4 + 5 * 2 = 2 for durability and 0 * 4 + -1 * 2 = -2 (and thus ignored as we only accept positive scores) for a total thus far of 2.
