Magic Cube

Convert the move format to one which can hold moves of the Megaminx and Gigaminx (in preparation for introduction of the Mega& Gigaminx Pretty Patterns)
Now we use 2 bits for the angle, 3 bits for the axis and 5 bits for the bitmap of layers. This totals 10 bits so 1024, but the whole thing will not spill over 3 digits, because in the Minxes we have total of 6 axis, not 8.

Fix the Solver broken by the change of move notation when importing Pyraminx Patterns :(

Progress with the 3x3x3 Solver.

Hopefully the only thing that remains to be done is to implement the RubikStateSolver.retCubeString().

More support for the 3x3x3 Solver: more of the actual 3x3x3 solver mechanism.
