***************************************************************************
* *
* 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. *
* step_history() replays the history, popping a dialog box before each *
* rotation - this is useful if you have developed an operator using the *
* model and you want to do the same rotations on a real cube. *
