Tag libIGCM_v2.4 second try. This version brings several new features and paves the road towards metrics handling within libIGCM.
- Data movement optimization (especially on Curie)

- Turn on BigBrother features to perform load testing on IPSL servers. This feature will be use to transport metrics results
- Turn on libIGCM instrumentation and send measures using the BigBrother feature.
- Add new 3D perturbation mechanism to generate ensemble members (3D pattern based instead of 2D white noise based)
- Can easily set ARCHIVE=WORKDIR in the UserChoices? section of config.card to avoid STOREDIR when SpaceName?=PROD
- New functions to modify def, xml and namelists from drivers
- IGCM_sys_rebuild_station will work also in the case where empty files has been produced by the model
- Netcdf 4 parallel support on Ada
- Airain support at CCRT

- Enhanced Ergon support
- bug fixes
