7### Moving coordinates 7* General idea: only improvement on generating pruning tables, no new
8* general cleanup 8 commands or anything else
9### Changes to Step and Solve
10* add a list of "helper" coordinates to every step
11* Probably nicer: instead of passing a cube pass a structure "cube description"
12 which can contain coordinates and one or more cubes.
13 This can also be used to avoid using index_epud too much in drfin
14 (it is slow because it goes through cubearray).
15* add a step->move(Cube) function, which may apply moves to the cube or just to
16 the coordinates
17* optimal solver: move the coordinates for the 3 orientations, but also the
18 cube so we can check the inverse

30### Changes to Step and Solve
31* Revolutionize: do everything based on coordinates, replace Cube with
32 CubeArray (or just 4 values, so consistency check is super easy);
33 remove tables for fast inverse.
34* No need for most of step data: just solve a list of coordinates
35 (+ associated pruning tables)
36* For steps that accept multiple solved states (e.g. drany):
37 just find a way to "merge" multiple steps as alternatives; or
38 offer multiple lists of coordinates as alternatives
39* De Bondt's trick: list of 3 coords (as indexes in coord array of the step)
40 that if evaluated to the same pruning value allow for de bondt's trick.
41* NISS: compute inverse based on current use moves just before switching,
42 using CubeArray; it is not too slow.
