* Solve a puzzle, showing the steps taken by the puzzle solver. The
* puzzle is initialized from stdin. The input file consists of triple,
* one per line, whitespace separated, of the form:
*
* row column value
*
* where row, column, and value are in the range 1..9.
*
* This is specifically a test of the "ambiguous" sudoku clues contained
* in puzzle4.txt. Personally I don't feel that a set of sudoku clues
* that require you to guess at a solution are legal, but I'm providing
* this interface since Ghica van Emde Boas (author of another Sudoku
* related class) raised the possibility.
