Sort candidate neighbors by edit distance. However;

the comparitor is currently broken such that:

(sort (distance-from "lock") ["look" "bonk"]) ; => ("bonk" "look")
(sort (distance-from "lock") ["bonk" "look"]) ; => ("look" "bonk")

Next step is figuring out what is wrong with distance-from.
Fix comparator. Tests green. Yay.
