CV pragmatics parsing example - first proper draft
 - needs to be run with the dippl browser setup because of canvas stuff
 - sorta works, uses standard distance fn, good distance fn required

 also, as an aside, the script shebang lines aren't really unix/posix compliant
 as I understand. Only a single argument is allowed (without spaces), so
   #!/usr/bin/env python                     is fine
   #!/usr/bin/env python --stack-size=65500  not so
   #!/usr/bin/python --stack-size=65500      is fine
 I made the changes locally to the 3rd option, but I haven't pushed in case it
 breaks something for others.
