Cube internal representation and moves now works
Corrected the function that calculate the probabilities and wrote the code that generate a solution.

I almost finished the implementation. I corrected the function that
calculate the probabilities at each step and wrote the code that
generate a solution for each ant. I tested the code but the
probabilistic choice doesn't seem to work properly. I still have to work
it out.
