7    o pkg/mom_common: variable horiz. viscosity in NH code
8      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
9        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
10      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
11        useBiharmonicVisc & useVariableVisc.
12      - fix old bug (already in 1rst implementation of variable horizontal viscosity
13        in calc_gw.F, version 1.27, 2006/06/20):
14        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
15        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
16      - change background horiz viscosity in vertical momentum (gW) to always be
17        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
18        any type of variable viscosity, e.g., viscAh/4Grid)
19      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
20        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
21        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
22        default viscAh,viscA4 is zero).
23  o model/src:  o model/src:
24    - extend length of drC & recip_drC from Nr to Nr+1.    - extend length of drC & recip_drC from Nr to Nr+1.
