-- a endofgame frame showing game results: win or lose
-
-- a Board class with cell being a 4 by 4 two-d array.
-- arrange strings according to an orientation: arrange(4 strings, dir)=cells
-  - dir: 0: align to left, 1: align to right, 2: align to top, 3:align to bottom
-  - e.g.: arrange({"abc", "bc", "dc", "efeh", 0}) gives the following board:
-         abc_
-         bc__
-         dc__
-         efeh
-  - arrange({"abc", "bc", "dc", "efeh", 0}, 3) gives the following
-     ___e
-     a__f
-     bbde
-     ccch
-- a new tile of 'a' or 'b' appears each turn somewhere, using some quasirandomisation e.g. (23 * n^2 + 79) mod 16.
-  - addtile(char, x, y)
-- the board transformation: board.trans(dir) = arrange(dir) . (fmap reduce) . getstring(dir). calls getstrings, then reduce on each row / column
-- board.getstrings(dir)= the strings according to direction dir. Inverse of arrange.
-- reduce(string)=string: reduce("baac")=="bbc"; reduce("aabb")=="bc"; and reduce("cbb")== "cc" instead of "d".
-- when one of the hjkl keys is pressed get the direction dir.
