Some cube grid plotting routines.

draw_tile_grid.m                :: Routine that plots the cube face geometry file.
 load_cs_grid.m                 ::  routines used by draw_tile
 make_cs_segments_and_patches.m ::
 load_cs_bathy.m                :: 

To make a plot

$ matlab
>> draw_tile_grid

this should produce a plot of the xc, yc, xg, yg, dxf etc... values for a six facet cube grid.
