1.01 is live

I've had the email telling me that version 1.01 is ready for sale. It should be in the App Store soon.

This fixes a couple of bugs that slipped through in the first release.

I've also optimized the puzzle location and number recognition to it should be a lot faster.

New features - obviously wrongly recognized numbers (that break the rules of a valid sudoku puzzle) now get marked in red.

I've been working on version 1.1 I'll post some interim screen shots tomorrow night.
