Message:

Update UKMO/nemo_v_3_6_STABLE_copy branch to revision 6228 of nemo_v_3_6_STABLE.
NB. Involved copying in new AGRIF directory (because that is what was done in the nemo_v_3_6_STABLE branch) so some continuity lost.
Custom merge into /branches/UKMO/nemo_v3_6_STABLE_copy/NEMOGCM: r6228 cf. r5767 of /branches/2015/nemo_v3_6_STABLE/NEMOGCM@6231
