Research best use of ref tag to use for notes and for links to external files (use type=link or type=note attribute)

Modify stylesheet in transcript-in-div to display arrow graphic after links, but not after notes.

As it happened, the URL of one of the links I was using included an apostrophe, which borked Mike's javascript code on the dynamic transcript page. With David's help, discovered the problem - only feasible solution is to correct the data.

To do: figure out how to add the arrow graphic after links in the dynamic transcript.
