* In MOM_ice_shelf_dynamics.F90 changes are made to calc_shelf_visc() and calc_shelf_driving_stress() to account for an irregular quadrilateral grid. In MOM_ice_shelf_initialize.F90 changes are made to initialize_ice_thickness_from_file() to correct masks at initialization.
* Changed indentation
* Changes are made to 'calc_shelf_visc()` to make computations of the velocity derivatives rotation-invariant. Changes in `update_ice_shelf()` utilize G%IareaT(:,:) instead of 1/G%areaT(:,:).
* Allocate shelf_sfc_mass_flux for dynamic ice shelf configurations
* Conditional allocation of ice shelf fluxes and data override call for sfc mass flux
* get rid of excessive line length
* call data override init for ice shelves
* A new subroutine change_thickness_using_precip() changes the ice thickness in response to the atmospheric mass flux
* Conditional calls to data_override
- Introduces a new flag: DATA_OVERRIDE_SHELF_FLUXES, which
if set to True, and ACTIVE_SHELF_DYNAMICS is also True, will
enable data_override capability for the surface mass deposition
(only avaialble for MOSAIC grid types)
* Changes are made to extrapolate_metric() in MOM_grid_initialize.F90 to avoid negative values at the southern boundary of the domain. This is done for grids extending over Antarctica.
* Reversed changes in MOM_grid_initialize.F90 to debug a regression test.
* Uncommented lines reading the ice velocity from file
* Changes to scaling factors and conversions of the 'sfc_mass_flux' parameter
* Remove unnecessary diagnostics for ice shelves from MOM_forcing_type
* Correct rescaling for data override of ice shelf sfc mass fluxes
* Add diagnostic rescaling for ice shelf mass fluxes
* Uncommented assignement of 'area_shelf_h(i,j)=G%areaT(i,j)' in MOM_ice_shelf_initialize.F90 and modified the four halo updates in MOM_ice_shelf.F90.
