  Description     : zipper-like comonad which works as a list, tracking a position

This Haskell library provides PointedList, which tracks the position in a 
non-empty list which works similarly to a zipper. A current item is always 
required, and therefore the list may never be empty. A circular PointedList 
wraps around to the other end when progressing past the actual edge.
