Crate math_audio_xem_common 

Common types and utilities for BEM/FEM room acoustics simulators

This crate provides shared functionality between BEM and FEM room acoustics simulators, including:

• Room geometry definitions (rectangular, L-shaped rooms)
• Sound source configuration (position, directivity, crossover)
• JSON configuration loading/saving
• Output JSON formatting
• Visualization utilities
