Message:

Possibility to store multiple initial states in one start/startfi. This is RETROCOMPATIBLE. New option ecrithist in run.def to write data in start/startfi every ecrithist dynamical timestep. New option timestart in run.def to initialize the GCM with the time timestart stored in start

+>> Added the possibility to store multiple initial states in one start/startfi
+>> New option 'ecrithist' in run.def to write data in start/startfi every ecrithist
+   dynamical timestep (default is to write it at the end of the GCM run).
+>> New option 'timestart' in run.def to initialize the GCM with the time timestart
+   stored in start (default is last time).
+>> This new feature is (supposedly) totally RETROCOMPATIBLE. Changes are:
+  - Time axis added in startfi
+  - Time axis can be longer than one in start/startfi
+  - Possibility to initialize the GCM with old start/startfi
+  - Compatibility with start2diagfi, newstart, testphys1d, expandstartfi
+  - Absolute date is stored in diagfi for less-than-a-day runs
+>> Quick documentation about dates :
+  - Day at the beginning of the start (integer) is stored in controle(4) 
+    for start and diagfi and controle(3) for startfi.
+  - Fraction of the day at the beginning of the start (real between 0 included and 1 excluded) 
+    is stored in controle(27) for start and diagfi and controle(29) for startfi.
+  - The "Time" variable stores all the dates from the beginning of the start (positive real) 
+    for start, startfi and diagfi
+  - Time is stored in start_archive in the "Time" variable.
+  - Time-related data in the controle field of start_archive are useless.
+For instance the i-th date of diagfi is controle(4)+controle(27)+Time(i)
