I have just uploaded Chapter 1 Introducing Calc to feedback.
I have gone through and accepted most of the changes of the French team,
added a couple of images. added Kieran's changes. Some of his suggestions
had already been considered in previous comments by myself and Chris.

Hope that last link is correct to go directly to the file. It doesn't look
quite right.
Cheers
