scirs2-integrate 0.5.0

//! Geometric integration methods
//!
//! This module provides structure-preserving numerical integrators for systems
//! with geometric properties such as:
//! - Lie group structure
//! - Volume preservation (divergence-free flows)
//! - Energy conservation (Hamiltonian systems)
//! - Momentum conservation (Lagrangian systems)
