provide a "classifier" client #9
Description
It would be great, when looking at a puzzle in a Sudoku book, to be able to quickly enter the puzzle and have the server tell me "you will not have to guess at any squares" or "you will have to guess at N squares but they will only have 2 possible choices at the time you guess" or ... This would be a nice "start classifier" that really gets at what most people want to know: Is Ariadne's thread required to solve this puzzle?
