 * This macro creates a virtual Rubik Cube and enable you to manipulate *
 * it.                                                                  *
 * You can chooose the size (number of small cubes along an edge).      *
 * It then makes the cube: large sizes can take a while.                *
 * It then displays several views of the cube.                          *
 * The central and largest view is an axonometric projection.           *
 * This has arrows around it which you can click on to rotate slices.   *
 * There are some text direction labels near the arrows: clicking on one *
 * of those rotates the whole cube. You have to click on the actual     *
 * letter: FreeCAD doesn't see clicks on the text background            *
 * Another view is an axonometric projection from the other side.       *
 * Another view combines views towards each face so as to               *
 * look like a net of the cube's surface unfolded.                      *
 * The macro maintains a history of the slice rotations you have done.  *
 * It puts three buttons at the top of the window.                      *
 * One undoes the last slice rotation and removes it from the history.  *
 * One saves the history to the clipboard as a sequence of function     *
 * calls which can be pasted into a macro which can then be called      *
 * to replay the same set of rotations. Thus you can save an "operator" *
 * (a sequence of slice rotation which does something useful).          *
 * The third button resets the cube to its initial state                *
 * and clears the history.                                              *
 * There are also some functions defined which can be called from the   *
 * python console window:                                               *
 * fix_reload modifies a restored FreeCAD save file to add the extra  *
 * views and interactive controls that this macro and its functions use; *
 * ramdomise randomises the cube;                                     *
 * reverse_history, reflectX_history, reflectY_history,           *
 * reflectZ_history, rotpX_history, rotmX_history,                *
 * rotpY_history, rotmY_history, rotpZ_history, and               *
 * rotmZ_history each replace the history by a version modified in the *
 * manner indicated - these are useful for creating modified operators. *

slowness = 500
 * 1) This parameter determines the speed at which slice rotations are animated
 * 2) If you have a faster computer you can increase the value
 * 3) This will make the animation smoother
 * 4) If you have a slow computer you can decrease the value
 * 5) This will make the animation faster but more jerky for large cubes

 * 1) This bit of code creates the basic cube model
 * 2) It is composed of faces rather than cubes because I haven't found a way of making
 * 3) a cube with different coloured faces
 * 4) Each face has a name and a label
 * 5) The name is persistent regardless of how the face moves about the cube
 * 6) The label changes and tells where the face is now: this is needed for fix_reload
