39	! Description:
40	! ------------
41	!> Data-output module to handle output of variables into output files.
42	!>
43	!> The module first creates an interal database containing all meta data of all output quantities.
44	!> After defining all meta data, the output files are initialized and prepared for writing. When
45	!> writing is finished, files can be finalized and closed.
46	!> The order of calls are as follows:
47	!> 1. Initialize the module via
48	!> 'dom_init'
49	!> 2. Define output files via (multiple calls of)
50	!> 'dom_def_file', 'dom_def_att', 'dom_def_dim', 'dom_def_var'
51	!> 3. Leave definition stage via
52	!> 'dom_def_end'
53	!> 4. Write output data into file via
54	!> 'dom_write_var'
55	!> 5. Finalize the output via
56	!> 'dom_finalize_output'
57	!> If any routine exits with a non-zero return value, the error message of the last encountered
58	!> error can be fetched via 'dom_get_error_message'.
59	!> For debugging purposes, the content of the database can be written to the debug output via
60	!> 'dom_database_debug_output'.
61	!>
62	!> @todo Convert variable if type of given values do not fit specified type.
