%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>.
