/* ----------------------------------------------------------------------
* Puzzle generation code.
*
* For this particular puzzle, it seemed important to me to ensure
* a unique solution. I do this the brute-force way, by having a
* solver algorithm alongside the generator, and repeatedly
* generating a random grid until I find one whose solution is
* unique. It turns out that this isn't too onerous on a modern PC
* provided you keep grid size below around 30. Any offers of
* better algorithms, however, will be very gratefully received.
*
* Another annoyance of this approach is that it limits the
* available puzzles to those solvable by the algorithm I've used.
* My algorithm only ever considers a single row or column at any
* one time, which means it's incapable of solving the following
* difficult example (found by Bella Image around 1995/6, when she
* and I were both doing maths degrees):
*
* 2 1 2 1
*
* +--+--+--+--+
* 1 1 | | | | |
* +--+--+--+--+
* 2 | | | | |
* +--+--+--+--+
* 1 | | | | |
* +--+--+--+--+
* 1 | | | | |
* +--+--+--+--+
*
* Obviously this cannot be solved by a one-row-or-column-at-a-time
* algorithm (it would require at least one row or column reading
* `2 1', `1 2', `3' or `4' to get started). However, it can be
* proved to have a unique solution: if the top left square were
* empty, then the only option for the top row would be to fill the
* two squares in the 1 columns, which would imply the squares
* below those were empty, leaving no place for the 2 in the second
* row. Contradiction. Hence the top left square is full, and the
* unique solution follows easily from that starting point.
*
* (The game ID for this puzzle is 4x4:2/1/2/1/1.1/2/1/1 , in case
* it's useful to anyone.)
