Constants Module

Mathematical, physical, and astronomical constants used throughout Brahe.

This module provides: - Mathematical constants (π conversions, angle conversions) - Time system constants (offsets, epoch definitions) - Physical constants (speed of light, astronomical unit) - Earth constants (radius, GM, shape parameters) - Planetary constants (GM values for solar system bodies)
