Code Coverage >90% (#2973)
No source code changes, just additional tests. FormulaParser appears unused, replaced by newer code in Calculation. However, it's a public interface, so probably shouldn't be deleted without first deprecating it. I have no strong feelings about whether that should happen. However, as long as it's part of the package, we may as well have some formal unit tests for it.
