showing first cube of new Cubes cutter

Started to create a sgCGroup *allCubes   in cutter.h .cpp,
to create the matrix of cubes to do bool intersection
finished middle section of cubies(9 cubes)

positioned 9 cubes according to cubie size and expanding towards the
outside of each side of the big cube.
only one section of the 3 for the cube.
finished top layer of cubies

finished creating top layer of cubies, to be used on boolean
intersection on the desired object
finished bottom layer of cube

finished building the botom layer of the cubies used to do boolean
intersection on 3d objects
good test on resizing tams of cubies and cube

some changes on size of big cube and of cubie
intersection algorith working OK!

succesful test on splitting a torus with the intersection algorith.
succesfull test on drawing the pieces.
now. to put them in the puzzle class and make them rotate
Merge remote-tracking branch 'origin/slicing'
