#1155 CF datasets with reversed coordinates not supported

[clynejp]

CF data sets with reversed coordinates are not supported. NetCDFCFCollection class expects longitude to run from west to east, and latitude from south to north. If they are reversed the data are not handled properly

To reproduce:

Translate Data/UKMet/GEMS_CO2_Apr2006.nc with momvdfcreate/mom2vdf and visualize results (they are garbage)

Note, the coordinates can be reversed with NCO using the command:

ncpdq -a '-latitude' GEMS_CO2_Apr2006.nc GemsReverse.nc

there 'latitude' is the name of the latitude variable.
