Auto step next (moves the selected item after run)
Min Max (checks VH SUMs and subtracts open fields and used numbers)
Min Max lines (checks VH SUMs and subtracts open fields and used numbers)
Remove dual halves (if to squares open we can remove possibles that are half the sum missing)
Double possible use (if two squares open the possibles are limited to the other possibles)
Locked lines forced use (30 on 4 is always 6,7,8,9 - if any number only occurs once it must be used)
Locked lines min (28 on 4 with one 5 will always be 4, [7,8,9])
Possible list (calculate all sums from possibles and remove those not used)
Block count (the sum on vertical squares equals sum on horizontals)
