in the parameter_list, the parameters G and Rm can now be empty, added paraemters zf_love and pt_factor; implemented varargs.wrap in methods unit, grid; renamed time.isvalid to time.isfinite; in the load_dir method, the maximum degree of models is match as they are loaded; revised the graceC20 methods and friends; revised the criteria to switch between radius or degrees in gauss_smoothing_type; in gauss_smoothing_name, handling infinite radius/zero degrees; implemented the zero_tide method to encapsulate handling the permanent tide; revised the resolve_degrees_orders method, with negative degrees meaning that nothing is returned; implemented the width2lmax method; in the scale_gauss and scale_spline methods, now handling infinite radius/zero degrees; in the plot method, fixed wrong order of cb.nan and colorbar, now returning figure and axis handles; in the load_gsm, load_icgem aux functions, revised the permanent tide correction; minor revision of the GetGRACEC20 aux function.
