Nutriscore algorithm implementated in java
Use example:
`final Product product = new Product.ProductBuilder()
.energy(1121f)
.fat(3f)
.saturatedFat(0.5f)
.sugar(0.5f)
.fiber(3f)
.proteins(9f)
.sodium(0.315f)
.salt(0.8f)
.build();
final String result = Nutriscore.getNutriscore(product, FoodType.GENERAL);`
