2x2 List Sorter

If you've ever seen a woman try on a dozen different dresses in a store, and then say, "I like this one better than that one, but I really like this other one better....", you'll understand the need for the 2x2 List Sorter. Same thing if you've ever presented a kid with 31 different ice-cream flavor choices at a Baskin Robins. It can be hard to get all your preferences sorted out, when you have to look at all the options at the same time. Along comes the 2x2 List Sorter to the rescue. Just feed it a text file of related choices (dress colors, fruit types, ice cream flavors), and the program will then help you step-by-step to figure out your most to least favorite.

Offers option to export the finished sort to text file.

The minimum number of button clicks required to achieve a sorted list is n-1,
and the maximum possibly required clicks is (n_squared / 2) - (n / 2), where n
is the number of items in the list.
