Improve DataIO documentation
Description
data-I/O is extensive and complicated enough that it would imho warrant a cookbook style .rst file which then is included in the sphinx documentation. Also, there have been complaints that the current documentation is too terse/lacking in quality, so the existing doc should be reviewed and the respective comments be updated or improved.
Proposal
- Write an intro to the usage of the dataI/O backend and make it part of the sphinx documentation.
- Update and improve the existing doxygen documentation.
- Include new DataManager into it.
How to test the implementation?
- review of quality is enough.
