  1. If area units on source grid file are in sq deg, convert to sq radians 

    This just applies to source grid files in the scrip format.

Without this fix, areas were assumed to be in sq radians, which led to
mapping weights that were off by about a factor of 3000 if areas were
actually in sq degrees.
