This is my thesis or whatever; this is how it should be read; this is what I intended, this is what I want to find out, and this is what I want you to think about. This is what I’d like you to not think about. This is an attempt to collect my own musings, answer some of my own questions, and pose a couple of new, more clever ones. This is not an attempt to do this and this. I know there are many gaps in my knowledge. I hope I have still got something of value to offer you. This project was undertaken around this time. If you want to have a go at the practical part of this project, click here. I’m me. You can get in touch with me here or here.
