16x16 TetraVex Solver updated (step-by-step visualization)

Hi everyone!

I have updated the solver I presented to you yesterday (16x16tetravex.xyz).

- Now it is able to produce a step-by-step visualization of the solving process. For this purpose, click on [Solve (step-by-step)];

- Today, during the conception of this step-by-step solution, I realized that my solver was in fact looking for ALL the solutions instead of one. I have corrected this issue: it is now at least 2x faster;

- The source code of the random puzzles generator is now online.

Thanks.

Guillaume
