%description
Implementation of icosahedral grids in three dimensions. The
spherical-triangular tessellation can be set to create grids with custom
resolutions. Both the primary triangular and their inverted
penta-hexagonal grids can be calculated. Additional functions are provided
that allow plotting of the grids and associated data, the interaction of
the grids with other raster and vector objects, and treating the grids as
a graphs.
