Three types: Angle, HourAngle, and Time, useful in astronomy applications.
This is a Dart port of the original Go library created by Sonia Keys and hosted at https://github.com/soniakeys/unit.
These types are all angle-like types. The Time type is at least angle-related. It has conversions to and from the other types and has a function to wrap a Time value to the fractional part of a day.
This package supports https://github.com/shawnlauzon/meeus, which implements a large colection of astronomy algorithms.
