7    o model debug options:
8      - Switch reading of debugMode from S/R INI_PARMS (parameter file "data", stored
9        in PARAMS.h) to S/R EESET_PARMS (parameter file "eedata", stored in EEPARAMS.h).
10      - Refine debug-msg printing selection (3 new levels):
11        debugMode  : controls printing of debug messages (sequence of S/R calls).
12        debugLevel : controls printing of algorithm-relevant auxiliary/debug messages
13         debLevZero =  0 ; /* level of disabled aux. msg printing */
14         debLevA =  1 ; /* level of minimum  aux. msg printing */
15         debLevB =  2 ; /* level of low aux. print (report read-file opening)*/
16         debLevC =  3 ; /* level of moderate debug prt (most pkgs debug msg) */
17         debLevD =  4 ; /* level of enhanced debug prt (add DEBUG_STATS prt) */
18         debLevE =  5 ; /* level of extensive debug printing */
19        New debugLevel default: with default debugMode value (=F),
20          = 2 (debLevB) or = 1 (debLevA) in case ALLOW_AUTODIFF is defined.;
21          and if debugMode=T, default debugLevel = 4 (debLevD).
22        Relation with previous settings:
23         debLevB (=2) corresponds to former debLevA (=1)
24         debLevD (=4) corresponds to former debLevB (=2)
25        Note:
26         a) if debugLevel=0, skip WRITE_GRID call when nIter0 > 0 (same as before);
27         b) default debugLevel=1 is convenient in AD runs (avoid many file opening msgs);
28            to recover previous default, set debugLevel=2 (e.g. AD-test hs94.1x64x5)
29      - Add new parameter (printResidualFreq, read from PARM02 namelist) to print
30        detailed CG solvers convergence; off (=0) by default, except if debugLevel=5.
31  o pkg/obcs:  o pkg/obcs:
32    - change OBCSfixTopo default from True to False (should not change the results);    - change OBCSfixTopo default from True to False (should not change the results);
33      keep OBCSfixTopo=T in verification-exp. seaice_obcs.      keep OBCSfixTopo=T in verification-exp. seaice_obcs.
