Description: Generate planar and spherical triangle meshes, compute
        finite element calculations for 1-, 2-, and 3-dimensional flat
        and curved manifolds with associated basis function spaces,
        methods for lines and polygons, and transparent handling of
        coordinate reference systems and coordinate transformation,
        including 'sf' and 'sp' geometries. The core 'fmesher' library
        code was originally part of the 'INLA' package, and implements
        parts of "Triangulations and Applications" by Hjelle and
        Daehlen (2006) <doi:10.1007/3-540-33261-8>.
