Updated the default values of remap_answer_date as declared during the specification of the wave_speed_CS, remapping_CS and regridding_CS to 99991231 (to use the very latest version of the algorithms) if these control structures are used without further initialization via optional arguments to their various initialization routines (wave_speed_init(), initialize_remapping() and initialize_regridding() or set_regrid_params()). In testing both via the TC tests and the MOM6-examples regression suite, all answers are bitwise identical, because every instance where these are used either does have an appropriate call to the initialization routine, or because (as is the case for remapping diagnostics) they are hard-coded to use the PLM remapping scheme, which is not impacted by this answer_date. It is conceivable, if unlikely, however, that there could be cases outside of the standard MOM6 code that are using this remapping capability without proper initialization of this flag, in which case answers could change. In addition, a comment was updated in the interp_CS_type indicating the cases that would be altered by changing the hard coded default answer_date there, but the default in that case was not changed. All answers and output are identical in the MOM6-examples and TC test suites.
