8    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
9       local variable (not in common block).
10    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
11      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
12      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
13        to work with SingleCpuIO.
14    o add "_d 0" to real constant of pkg/cfc subroutines ;
15       update exp. cfc_exemple & tutorial_cfc_offline output files.
16    o multi-threading and IO:
17      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
18        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
19      - barrier before and after reading.
20      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
21      - avoid using MDS_WRITELOCAL for LAND pkg output.
22      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
23        common-block variables ; Allows multi-threading with master-thread IO.
24  o change default MAX_NO_THREADS from 32 to 4 ;  o change default MAX_NO_THREADS from 32 to 4 ;
25    and stop cleanly when MAX_NO_THREADS is too small.    and stop cleanly when MAX_NO_THREADS is too small.
