**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.
