Employs triangular tessellation to refine icosahedra
defined in 3d space. The procedures can be set to provide a grid with a
custom resolution. Both the primary triangular and their inverted penta-
hexagonal grids are available for implementation. Additional functions
are provided to position points (latitude-longitude data) on the grids,
to allow 2D and 3D plotting, use raster data and shapefiles.
