[MITgcm-support] Best practice for cubed-sphere grid generation?

[Angela Zalucha]

Jason:

radius_fromHorizGrid rescales the physical distances and areas on the 
globe for a different size planet at run time, which was added slightly 
over a year ago.  I also have a short matlab script that I used prior to 
this that does the same thing offline to the tile.* files (I had no idea 
one already existed at mitgcm.org).
