The Sudoku Project #2

This is the second part of a series of codes. Previous one here: The sudoku project #1

In this part we'll make the next step and make a function that solves the sudoku. Later it will be easy to modify such a function in order to use it as generator as well. The puzzle to be solved will be passed as array of rows, where each row is an array and the blanks are represented by zeroes.

Take a look in the JS section to see how that works :D

I have tested it over and over again, but would appreciate if you do some tests of your own.
