[CF-metadata] grid_mapping

[Karl E.Taylor]

Dear all,

Is this system general enough? The French (LODYC) have a grid for their ORCA model in 
which both poles are located in the N. Hemisphere.  (Which is the north pole?).  
The HOPE model at MPI can have 3 poles (at least in one configuration).  I think we 
should try to make CF general enough to accommodate these.
