[computer-go] C++ parameter passing

Taking a step back, zobrist_numbers[][] could be a private member in a
class, and remove() could be a function on that class.

...actually I guess this is a member function of a class to store a
zobrist hash? In that case zobrist_numbers should be a static data
member of that class shouldn't it?

Anyway, whatever, in the terms of Martin Fowler's Refactoring book,
passing a multidimensional array as a parameter to a function is a
"smell" and you should refactor.
