New section on Design Notes

For now I've removed my section on Stock Photography as I'm not working so much on that. Too much competition for very little return has made it unrewarding, and all the large stock photo agencies can afford to be picky. I have added a new web page on Design Notes,  intended for sundry articles on commerce and product design. Starting with the thorny problem of costs, markup and margins for non-accountants.
