enterNumberfunction
Write a number into a cell (0 empties it). Its own pencil marks go, and with tidy (the default)
the number comes out of the pencil marks of every cell that shares a group with it, as a person
with a pencil would rub it out. Nothing happens to a printed cell, or when the cell already holds
that number.
