+Refactor nominal depth in ALE code#381
Merged

Conversation
Refactored 6 files in the ALE directory to calculate the nominal depth in thickness units in a single place (it is done in regridding_main now) and pass it to the various places where it is used, in a preparatory step to modify how this calculation is done in non-Boussinesq mode. There are new arguments to several publicly visible routines, including: - Add non_depth_H arguments to hybgen_regrid, build_zstar_grid, build_sigma_grid, build_rho_grid, build_grid_HyCOM1, build_grid_adaptive, build_adapt_column and build_grid_arbitrary - Add optional zScale arguments to build_zstar_grid and build_grid_HyCOM1 - Add unit_scale_type arguments to regridding_main, ALE_regrid_accelerated and ALE_offline_inputs Also eliminated an incorrect rescaling GV%Z_to_H facto when calculating the total column thickness from the layer thicknesses when an ice shelf is used with a Hycom grid. This would have caused dimensional consistency testing to fail. Added the new runtime parameters HYBGEN_H_THIN, HYBGEN_FAR_FROM_SURFACE HYBGEN_FAR_FROM_BOTTOM, and HYBGEN_DENSITY_EPSILON to set previously hard-coded dimensional parameters used in the Hybgen regridding code and store these values in new variables in hybgen_regrid_CS. Two of these are no longer passed to hybgen_column_regrid as separate parameters. By default these new runtime parameters recover the previous hard-coded values. Also eliminated an unused block of code in build_rho_column. Several comments documenting variables or their units were also added. All answers are bitwise identical, but there are 4 new runtime parameters that would appear in some MOM_parameter_doc files and there are changes to the arguments to 11 routines.
