Now it extracts nav_lon and nav_lat from the seas list when you provide  in lstseas of the ohc_Arcticreg1

Added the cdo version 1.6.3 option, in case we have to remove the valid_min/max attributes to avoid values out of that range to be replaced by NaN or very high numbers

Changed the way of copying mask.regions, if it exists it doesn't copy anything. I noticed when introducing other changes

"Needed the changes for overwriting the masks everytime I run setup.development"

Sorted out the problem: not creating symbolic links with the mesh.masks, because it already existed, however the mask could have changed during the time, and it must be remade. Now it copies the mask and overwrites if it already exists

Changed documentation for ohc function and conditional if you make a mistake choosing the name of the Arctic region

Remove path to Virginie's home for cdfheatc-cfu as it is now the same as the one included in the module environment
