[netcdf-java] ESRI implementation of ellipsoidal-earth

Apparently ESRI is willing to add support for CF 1.5 grid_mapping attributes 
for ellipsoidal-earth/geodetic-datum definitions in the Grid Mappings and 
Projections specification.

They are looking for sample data, especially using ellipsoidal parameters 
(semi_major_axis/semi_minor_axis/inverse_flattening). Does anyone have any?

Also, they are wondering what to use for the default ellipsoid when these are 
not specified. It seems to me the obvious candidates are 1) spherical earth 
with a standard radius, or 2) WGS84 ellipsoid.
