Description: Generate constrained Delaunay triangulation meshes for use
        with stochastic partial differential equation (SPDE) spatial
        models (Lindgren, Rue and Lindstroem 2011
        <doi:10.1111/j.1467-9868.2011.00777.x>). Provides automatic
        mesh generation from point coordinates with boundary
        constraints, Ruppert refinement for mesh quality, finite
        element method (FEM) matrix assembly (mass, stiffness,
        projection), barrier models, spherical meshes via icosahedral
        subdivision, and metric graph meshes for network geometries.
        Built on the 'CDT' header-only C++ library (Amirkhanov 2024
        <https://github.com/artem-ogre/CDT>). Designed as the mesh
        backend for the 'tulpa' Bayesian hierarchical modelling engine
        but usable standalone for any spatial triangulation task.
