+ Matthieu Leclair & Gurvan Madec

+=== Branch ===
+DEV_r1837_MLF
+----
+
+=== Description ===
+
+Introduce the modified Leap-Frog Robert-Asselin filter to fit the one presented in Leclair and Madec Ocean Modelling (2009).
+
+The main remaining modifications concern : 
+
+(1) forcing terms as a mean between time step n-1/2 and n+1/2 (sbcmod)
+
+(2) Asselin filter: remove the forcing from the filter (dynnxt, tranxt, traqsr)
+
+(3) semi-implicit hydrostatic pressure gradient : change the coefficients to take into account the Asselin filter parameter (tranxt)
+
+This update is part of the LOCEAN.8 task (Update of the ocean physics) due by June 25th
+

+=== Testing ===
+Testing could consider (where appropriate) other configurations in addition to NVTK].
+
+||NVTK Tested||!'''YES/NO!'''||
+||Other model configurations||!'''YES/NO!'''||
+||Processor configurations tested||[ Enter processor configs tested here ]||
+||If adding new functionality please confirm that the [[BR]]New code doesn't change results when it is switched off [[BR]]and !''works!'' when switched on||!'''YES/NO/NA!'''||
+
+(Answering UNSURE is likely to generate further questions from reviewers.)
+
+'Please add further summary details here'
+
+ * Processor configurations tested
+ * etc----
+
+=== Bit Comparability ===
+||Does this change preserve answers in your tested standard configurations (to the last bit) ?||!'''YES/NO !'''||
+||Does this change bit compare across various processor configurations. (1xM, Nx1 and MxN are recommended)||!'''YES/NO!'''||
+||Is this change expected to preserve answers in all possible model configurations?||!'''YES/NO!'''||
+||Is this change expected to preserve all diagnostics? [[BR]]!,,!''Preserving answers in model runs does not necessarily imply preserved diagnostics. !''||!'''YES/NO!'''||
+
+If you answered !'''NO!''' to any of the above, please provide further details:
+
+ * Which routine(s) are causing the difference?
+ * Why the changes are not protected by a logical switch or new section-version
+ * What is needed to achieve regression with the previous model release (e.g. a regression branch, hand-edits etc). If this is not possible, explain why not.
+ * What do you expect to see occur in the test harness jobs?
+ * Which diagnostics have you altered and why have they changed?Please add details here........
+

+=== System Changes ===
+||Does your change alter namelists?||!'''YES/NO !'''||
+||Does your change require a change in compiler options?||!'''YES/NO !'''||
+
+If any of these apply, please document the changes required here.......

+=== Resources ===
+!''Please !''summarize!'' any changes in runtime or memory use caused by this change......!''
+
+----
+=== IPR issues ===
+||Has the code been wholly (100%) produced by NEMO developers staff working exclusively on NEMO?||!'''YES/ NO !'''||
+
+If No:
+
+ * Identify the collaboration agreement details
+ * Ensure the code routine header is in accordance with the agreement, (Copyright/Redistribution etc).Add further details here if required..........
