The web service that can create a random classical Sudoku board and that can validate successive moves. It also be able to recognize and indicate if the Sudoku is finished.

1. To generate a board make a GET request. 
    http://127.0.0.1:8080/board/
return a json with fields   
              - id of the board,   
              - board values (0 is blank cell)

{
"id" : 8218678219165386788,      
"value" : "530070000600195300098000060800060003400803001700020006060000280000419005000080079",
}

it means: 5 3 0 | 0 7 0 | 0 0 0 6 0 0 | 1 9 5 | 0 0 0 0 9 8 | 0 0 0 | 0 6 0

            8 0 0 | 0 6 0 | 0 0 3
            4 0 0 | 8 0 3 | 0 0 1
            7 0 0 | 0 2 0 | 0 0 6
            
            0 6 0 | 0 0 0 | 2 8 0
            0 0 0 | 4 1 9 | 0 0 5
            0 0 0 | 0 8 0 | 0 7 9

2. To do a move on the board using POST request.    
  Example: http://localhost:8080/validatemove?id=888895882976226&x=1&y=3&value=7
  x,y is coordinates, id is id of the board

could return: INVALID, VALID, COMPLETE or exception
