Unit testing constants ...

Hi all,

Unit testing is a big part of Cmd4 with 9268 running successfully in under a minute before every submission. I'm always looking for new ways to benefit from unit testing.

• This update checks not only if all constants that are defined are used, but it also scans all the source files for constants that were not defined. There were actually three used that were not defined, but just affected a possible FakeGato config of the Google file system.

Take care,
John Talbot
