- Implement robust surface area and volume computation for polymesh_t
- Support arbitrary polygonal faces (triangles, quads, etc.) via fan triangulation
- Add vector math utilities: cross, dot, norm, and signed volume
- Validate algorithm correctness using unit cube test case
- Ensure right-hand rule compliance for accurate volume sign
Test: Added test case with unit cube (8 vertices, 6 quads)
Expected: area = 6.0, volume = 1.0 → actual results match
- Simplified and unified constructors for `integrator_t` to improve usability and maintainability.
- Enhanced `find_v_intersections_at_u` with robust handling of vertical edges and improved numerical stability.
- Refactored `is_point_inside_domain` to reuse existing intersection logic, eliminating code duplication.
- Adjusted interface to align with revised expectations around `parametric_plane_t`, which previously caused inconsistencies.
- Extended design to support multi-face integration (previously limited to single face); volume-related logic temporarily commented out for clarity.
This version is compilable, but not yet runnable due to nullptr issues in primitive_process during object creation. Integration framework is now structurally ready for multi-surface extension once initialization is fixed.
- Implemented Gaussian-Legendre quadrature method in gauss_integrate_1D.
- Implemented tanh-sinh quadrature method in tanh_sinh_integrate_1D.
- Both methods accept a function, integration limits [a, b], and the number of quadrature points (q).
