Magic Cube

Simplify TwistyObject's API.

Reename ObjectList to a more logical ObjectType.

Simplify ObjectList: now there's just one object per size.

Remove all files that have been separated into a new library 'objectlib'

Prepare the 'objectlib' package to be separated into a library module

Refactoring: split the 'objects' package into two, 'objects' and 'objectlib'.
The point: we're going to need to move the 'objectlib' stuff into its own library module, and that's because we're going to create a new app module which needs access to it.

Move the TwistyObject.retCubePosition() to the solver.

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.

Make it possible to have some objects created from dmesh, and others - bootstrapped programmatically.

Cube Control: step 2.
