## Version 0.7 (in progress)
* Allow comments in ini files (lines starting with `;`)
* Ini files support flags (only read)
* Ini files support flags
* Ini files support vectors
* Ini files support subcommands (only read)
* Ini files support vectors (only read)
* Added CodeCov code coverage reports
* Lots of small bugfixes related to adding tests to increase coverage
* Error handling now uses scoped enum in errors
* Reparsing rules changed a little to accommodate Ini files. Callbacks are now called when parsing INI, and reset any time results are added.
* Adding extra utilities in seperate files version only, `Timer` (not needed for parsing, but useful for general CLI applications).
* Adding extra utilities in full version only, `Timer` (not needed for parsing, but useful for general CLI applications).
