    em_case :   path to the WRF directory that has the compiled
                namelists, soundings, links to executables, etc. for a
                specific compile setup, for example, em_global_mars or
                em_les. These are the files that will be copied into a 
                run directory, run_dir
    run_dir :   name of the directory in which the WRF simulation will
                be run (i.e., run directory, i.e., run_dir). This must
                be the complete path to the run diretory. 
**NOTE**: Must be executed in the main WRF directory, after the code is
          compiled/built.
