- googletest command-line output lists a nice summary of failed tests at the end, doctest's doesn't
- string test case names in doctest make IDE file structure view useless
- googletest has VS support
- doctest development stalled
other changes:
- get rid of doctest::skip(), all tests run now.
(was only applied to 3 tests: "winding", "mountain", "base1")
- no more "isLocked" - use getSource directly (locked is a confusing name)
- no more split parse/setValue functions. there's only one entry point each now, and all they do is pass along the source passed to it from its parser.
- no separate setters, use setValue(value, source)
- add a "game target" source, which is low priority and indicates to the user that the value would have been default but was changed to a better value for the game target
