1 /* Converts point precipitation data in struct tdata to hrap grid. The
2  20 closest tstations are precalculated for each grid point - this
3  speeds computations for data sets with many precipitation points.
4  If there are no good precipitation points for a grid point, then
5  a recalculation is made using all precipitation points. 1/R**2
6  interpolation is used. If requested, the final interpolation
7  is scaled using seasonal isohyets. The grid is saved as a disk
8  file and used later for a raster or vector (HRAP) plot. */
