Changes for version 0.17
- Two killer bugs were discovered in 0.07 and so the entire module was reimplemented using test-first development.
- Devel::Cover was used to make sure all the code pathways are covered. There are a few branches not followed but they are mostly in areas that perl doesn't define execution order like the cleanup of globals during global destruction.
- The undocumented ->Dump method produces lisp-like data. In scalar or list context just returns its value, in void context it prints it.

Recompute values as needed to use post facto changes to input variables
