Description: ! ------------ !> Data-output module to handle output of variables into output files. !> !> The module first creates an interal database containing all meta data of all output quantities. !> After defining all meta data, the output files are initialized and prepared for writing. When !> writing is finished, files can be finalized and closed. !> The order of calls are as follows: !> 1. Initialize the module via !> 'dom_init' !> 2. Define output files via (multiple calls of) !> 'dom_def_file', 'dom_def_att', 'dom_def_dim', 'dom_def_var' !> 3. Leave definition stage via !> 'dom_def_end' !> 4. Write output data into file via !> 'dom_write_var' !> 5. Finalize the output via !> 'dom_finalize_output' !> If any routine exits with a non-zero return value, the error message of the last encountered !> error can be fetched via 'dom_get_error_message'. !> For debugging purposes, the content of the database can be written to the debug output via !> 'dom_database_debug_output'. !> !> @todo Convert variable if type of given values do not fit specified type. !--------------------------------------------------------------------------------------------------!
