Units in the nutrition module

Currently, we can only enter food quantities in grams. I do understand the reasoning behind this, as it’s much more accurate than, say, “cups,” and helps prevent errors. But for some items, like an egg or an apple, it would be handy to be able to count them by the piece; after all, customers don’t always have a scale with them. I’d also like to be able to add fats like olive oil by the tablespoon or soup spoon.
