2009-06-12 version 1.0
	Created first version based on Michael Gillett's 1996 javascript program. My version differs because:-
	1. It includes more camera formats.
	2. It is HTML 4.01 Transitional - though it probably needs some adjustments for compliance.
	3. It uses CSS.
	4. It is converted to UTF8 - means we can use the proper infinity symbol rather than "inf",
	5. The source code in the original was a bit messy and had a number of little errors. This version (hopefully) fixes most of these.
	6. This version includes information about the various formats.
	7. Includes links to various references.
	8. Circle of confusion calculations based on d/1500 as per Wikipedia article rather than d/1720.
	9. Javascript moved to head area from the body area.
