Feature/#10 serialization ideas for sample document

Summary

Possible ideas for rendering the sample text in a viewer.

Leiden Conventions have been considered as far as possible to make these suggestions feasible for all kinds of editions.

Use Cases

If thought through and implemented thoroughly these suggestions might help to build a generic viewer. Project specific changes might occur, however, since we didn't talk over these suggestions with the scholars (which has been a mutual decision).

Changelog

• I added a statement to the CHANGELOG.
