TO DO LIST on alpha v4.0

Various issues to be solved before the beta version :[[BR]]

• ISOMIP & OVERFLOW ==>>> do 1 experience for 1 tests (ln_zps, dynhpg, .. etc)

• Closea ==>>> after D.Storkey modification of dev_merge_2017: NEED to re-create ORCA_R2_zps_domcfg.nc file: => nn_closea = 1 + run make_closea_masks.py script in TOOLS/DOMAINcfg of Dave to generate closea_mask field, that it is added to the new ORCA_R2_zps_domcfg.nc file.

==>>> TEST ORCA2 in forced mode with /without closea. N.B. leave ln_cosea = .false. in tha namelist_cfg

• Closea for ORCA1? ==>>> just verify with Christian/Julie? if for eORCA1 the domain_cfg file has closed seas, and explain them how to re-create new input files, to be able to run eORCA1 iwth the 4.0 alpha release

• Long run of ORCA2 ==>>> gurvan tested (jannuary 9th) and after 180 timesteps code blows up (maybe ice? change nn-fsbc to 1?)

• Create a climatology of ice to use "iceif" (sort of ocean offline) ==>>> if climatology (clem/martin) is created so keep the icif option, if not remove this option from the code?
