Picking the top of anything is hard. Humans are better at comparing two items at a time, but it's even harder when you add multiple people.
Modify the list in ./data/ with each line being an option, then run the app:
cargo run
The app will prompt you asking how many people are ranking the list, then it'll go through and rank all the items two at a time with each user, then average the lists and show you the output.
