dynamic in the global workflow. This is to prepare the RT namelist
for the RT-GW bridge PR.

This commit changes a couple of the parameters in
cpld_control_sfs to bring it in line with the Global
Workflow parameter values.

This commit addresses the issue in default_vars.sh where
ATMRES is reset in the export_cpl() call to C96.
Default values will now only be set if the resolutions have
not been previously set.
