Complete Issue #6

The work necessary to complete issue #6 is attached.

The only thing that I know you may want to change is my use of the label on the parent protocol page (see generated output for updated example_with_messages.avsc file). I did not include the label inside of the <a> tag as I am not a big CSS guru who was able to figure out how to get the <a> to be styled like it is in the nav panel on the left. 

I also modified the example schema to include use of an enumeration.

Let me know if you have any questions on what I did to get all of this up to date!
