Demo standalone bric file that extends the activity database
closurify existing unit tests
some changes left after backing out attempt to wrap the brixlib in an IIFE

I ran into 2 problems. 1st was that w/ the language set to ES5 strict, goog.global was incorrectly set. The 2nd was that an issue w/ the closurebuilder prevents spaces in the compiler flag values. I've posted to the closure library group to see if there are suggestions.
added brixlib-compiled to some sample pages removed scripts now in brixlib
added output_wrapper

I got the syntax to make it work from the closure-library group.
