7    o pkg/monitor (angular momentum):
8      - do not add Eta contribution to the total AM if using rigid-lid;
9      - correct for Adams-Bashforth in zonal-wind part (instead of in AM_eta).
10      - horizontal discretisation: compute Zonal wind contribution separately for
11        each component (instead of from cell centered averaged) and use the 4
12        grid-cell corner averaged value of Omega*(R*cos_Phi)^2 in AM_eta part.
13      - Check that AM is conserved with linear dynamics (momAdvection=F and linear
14        FreeSurf) if using vectorInvariant momentum.
15    o model/src (horizontal grid):
16      - move initialisation of all horizontal grid arrays to null value
17        from specific horizontal grid S/R to main S/R INI_GRID;
18      - add 2 new arrays to project model C-grid velocity on to zonal direction
19        (similar to AngleCosC & -AngleSinC but at U and V point location) and
20        compute them in S/R CALC_GRID_ANGLES.
