- fix the muti-threading with master-thread IO : use AIM_WRITE_PHYS     instead of AIM_WRITE_LOCAL. - fix MNC snap-shot (multi-tiles was wrong ; not compiling if #undef     ALLOW_CLR_SKY_DIAG); tested and identical to MDS output. - no attempt to get MNC snap-shot in multi-threaded config; aim_tend.*.nc    still to be fixed.
