Branch 2019/dev_r10721_KERNEL-02_Storkey_Coward_IMMERSE_first_steps. Begin merge prepartions by merging changes on the trunk since this branch creation. Do this in staged commits in case of issues. First stage is to merge and commit changes to cfgs directory (cd cfgs; svn merge -r 10721:11740 svn+ssh://acc@forge.ipsl.jussieu.fr/ipsl/forge/projets/nemo/svn/NEMO/trunk/cfgs ./)
