Angle normalization, conversion, and distance functions.
Circular mean and minimal covering arc for sets of angles on a circle.
Coordinate-system transforms on the sphere.
Keplerian orbital mechanics.
Small numeric helpers shared across the library.
3x3 matrix operations, primarily for rotations.
Time-scale helpers for astronomical computation.
3D vector operations on {x, y, z} tuples.
