For those who have downloaded the latest arc egress example, sorry! David Baldacchino pointed out a math error in my work. I've fixed it and have posted new files at the site again. I also tweaked the schedule formatting a tiny bit.

By the way, David provided me with an example that includes the arrow and dot but they can't resize with scale change so I haven't included that...yet.
