Liberate current implementation of "Calc DSL"
(Copyright headers will be added in the next commit; these are the original files, unaltered in any way.) The internal project name at LoVullo is simply "Calc DSL". This liberates the entire thing. If anything was missed, I'll be added later. To continue building at LoVullo with this move, symlinks are used for the transition; this is the exact code that is used in production. There is a lot here---over 25,000 lines. Much of it is in disarray from the environment surrounding its development, but it does work well for what it was intended to do. (LoVullo folks: fork point is 65723a0 in calcdsl.git.)
