Revision 5cf34c5f

Added by Leszek Koltunski about 4 years ago

Make chances to randimoze a given row when scrambling dependant on the type of Object.

The point: in case of the Cube, all rows should have equal chances. In case of the Pyraminx, the smaller the row, the smaller the chance should be. In particular the trivial 4 corners of the tetraherdon should have a very small chance to be selected.
