// Package numerics provides the numerical primitives used by the trajectory
// engine: regular-grid multilinear interpolation, monotone bisection, and
// a generic explicit Runge-Kutta-4 integrator with binary-search refinement
// of a termination point.
//
// The package has no dependencies on any domain type. State and derivative
// types are generic, and all coordinate-wrap or unit-conversion semantics
// live in the caller.
//
// All algorithms are documented in docs/numerics.tex.
