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.
