cdo sellevel,0 selects depth 0m which works fine when the depth axis is not defined; nemo does not read the depth axis so it does not matter at runtime whether the depth axis is defined or not; when building the restarts, it is safer to define the depth axis to avoid mistakes; then ncks -d z,0 needs to be used rather than cdo sellevel,0 to work on restarts for which the depth axis is defined; this commit needs to be reverted in case someone notices a case for which ncks -d z,0 does not work and another more general solution should be searched if this happens

- changing the case of string from upper to lower or vise versa should be treated in a similar way in all sets of templates...

- Improved the use of perturbation of IC's w.r.t. atm, oce and ice by eliminating the use of parameters PERT_method and PERT_member and introduced new set of parametes ATM_ini_member, OCEAN_ini_member and ICE_ini_member into expdef.conf.

Here is below the link where user can see the available set of IC's for atm, oce and ice and respective members:

- In order to generate the COMPLETED files uniquely along with monitoring information the AS-HEADER and AS-TRAILER kind of parameterizations introduced for local and remote jobs separately into all sets of templates.

- generalized ecearth3 and nemo3 templates a bit...

nemo3: a new set of templates has been introduced for running nemo-standalone experiments (for reference please give a look at m022)

- ecearth3-spin templates has been created where post-processing will be perfromed w.r.t. pp-tool designed by Klaus...

- also fixed a few conflicts
