IOW ESM minimal complete setup

This a minimal setup for the IOW ESM (compatable to version 1.04.00). The coupled run is performed for 9 days (1959-01-01 to 1959-10-01) in chunks of 3 days. The atmospheric model is CCLM (version 5.00) with 0.22° horizontal resolution for the Eurocordex domain. The oceanic model for the Baltic Sea is the MOM5 model with 3nm horizontal resolution acompanied by the ERGOM ecosystem model. The forcing for CCLM is generated from the ERA5 reanalysis data. The setup is constructed for the HLRN supercomputer and has to be adapted for other target machines. See the related documentation at https://sven-karsten.github.io/iow_esm/intro.html.
