* Add Example wrapper in order to display test failures inline when running in Xcode. * Stop using Swift 5.1-only features so we can compile on Xcode 10.2. * Wrap strings in Example. * Add Changelog entry. * Wrap all examples in Example struct. * Better and more complete capturing of line numbers. * Fix broken test. * Better test traceability. * Address or disable linting warnings. * Add documentation comments. * Disable linter for a few cases. * Limit mutability and add copy-and-mutate utility functions. * Limit scope of mutability.
