First marked release

Implementation has flip-flopped a few times now, so chronoline needs versioning to ensure compatibility.

Hopefully issues #8 and #13 are both resolved by this release. After trying UTC to normalize daylights saving time and discovering that it caused more problems, I reverted back to local time zones with DST correction.

stripTime is now added as a mutator to Date. If you decided to use this externally, please refactor accordingly.
