Renamed ZoneInfo in a doctest to avoid confusion with tharsis.prof ZoneInfo.
Fixed a typo.
Moved ZoneInfo out of ZoneRange so we don't need to do ZoneRange!EventRange.ZoneInfo
Minor cleanup.
Refactored ZoneData init to a package function (for other zone ranges).
Renamed `Event.startTime` to `Event.time`.
Added a 'chunky' event list (+ ranges) to support real-time profiling.
