Option NETCDF4_ENABLED==1 now produces output in netCDF-4 classic model
rather than full netCDF-4.

time-slice output files.

parameters for basal sliding.
Optional spatial smoothing of the basal sliding coefficient
implemented (parameter C_SLIDE_FILTER_WIDTH).
New global variables (defined in sico_variables_m):
c_slide_init, gamma_slide_inv, sub_melt_flag.

(by Shreyas Sunil Gaikwad).

sico_specs_v5_grl16_bm4_ss25ka.h replaced by
sico_specs_v5_grl16_bm5_ss25ka.h
(SIA, 16 km resolution, using the new BedMachine V5 topography).

now always written in uncompressed, classic netCDF-3 format.

rather than full netCDF-4.

for better visibility.

run-specs headers and script get_input_files.sh updated.

It can generate the NetCDF files for the physical parameters
required by SICOPOLIS.

maximum ice extent constrained by prescribed mask.

and resolution_doubler.F90.

*_ser.nc and *_core.nc.

(by the sico_init routines).

if NetCDF-4 format is enabled.

'deflate_level' and 'shuffle' for variable compression under NetCDF-4.

controlled by the new preprocessor switch NETCDF4_ENABLED (0/1).
Default is NetCDF-3 Classic as before.

relative to xmin, xmax, ymin, ymax of the computational domain.
If a defined ice core is out of the domain, execution does not stop
any more, only a warning is written.

now only performed for physical-parameter files in ASCII format.

netCDF commands to facilitate error detection.

sico_specs_v5_grl20_ss25ka.h replaced by sico_specs_v5_grl16_bm4_ss25ka.h
(SIA, 16 km resolution, using the new BedMachine V4 topography).
Counterpart for Antarctica renamed
sico_specs_v5_ant40_ss25ka.h -> sico_specs_v5_ant40_b2_ss25ka.h.

changed from ASCII (not available any more in the repository) to NetCDF.

(max./min. number of nonlinear iterations for the SSA/SStA solver)
changed from (10,1) to (25,2).

Settings of TOL_ITER_SSA and N_ITER_SSA changed.

minimum number of iterations N_ITER_SSA_MIN (default 1).

in the run-specs headers.

Parameter CHECK_RES_IMAX_JMAX mentioned under "Domain XYZ".
