Description of your issue or question

When you create an out-of-the-box HEMCO standalone run directory, there is no Restarts/ folder:

$ ls
build/                          HEMCO_Diagn.rc        HEMCO_sa_Spec.rc   README
CodeDir@                        HEMCO.log             HEMCO_sa_Time.rc   rundir.version
HEMCO_Config.rc                 HEMCO_sa_Config.rc    hemco_standalone*  runHEMCO.sh*
HEMCO_Config.rc.gmao_metfields  HEMCO_sa_Grid.4x5.rc  OutputDir/

This causes HEMCO standalone simulations to die with an error at the end of the run:

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

In Nccr_Wr, cannot create:  Restarts/HEMCO_restart.201907020000.nc

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Code stopped from DO_ERR_OUT (in module NcdfUtil/m_do_err_out.F90) 

This is an error that was encountered in one of the netCDF I/O modules,
which indicates an error in writing to or reading from a netCDF file!

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Note: The following floating-point exceptions are signalling: IEEE_UNDERFLOW_FLAG IEEE_DENORMAL
STOP 999

The simple fix will be to add a directory creation command in the HEMCO/run/createRunDir.sh script.

Ooops I might have been on an older branch.
