create_grid_offline

INTERFACE:

   subroutine create_grid_offline()

DESCRIPTION:

   Generate land model grid when mode is offline.
   Surface grid edges -- Grids do not have to be global. To allow this, grids 
   must define the north, east, south, and west edges:
   If namelist variable mksrf_offline is not the empty string, then the land model
   grid will be generated at run time using the settings of the
   namelist variables
      o mksrf_offline_fnavyoro : 20 min navy orography dataset
      o mksrf_offline_edgen (edge(1)) : northern edge of grid (degrees): >  -90 and <= 90
      o mksrf_offline_edgee (edge(2)) : eastern edge of grid (degrees) : see following notes
      o mksrf_offline_edges (edge(3)) : southern edge of grid (degrees): >= -90 and <  90
      o mksrf_offline_edgew (edge(4)) : western edge of grid (degrees) : see following notes
   For partial grids, northern and southern edges are any latitude
   between 90 (North Pole) and -90 (South Pole). Western and eastern
   edges are any longitude between -180 and 180, with longitudes
   west of Greenwich negative. That is, western edge >= -180 and < 180;
   eastern edge > western edge and <= 180.
   For global grids, northern and southern edges are 90 (North Pole)
   and -90 (South Pole). The western edge of the longitude grid starts 
   at the dateline if the grid is generated (the longitudes for each grid 
   cell correspond with the edges (i.e., range from -180 to 180)).
