Document procedure for new Reader type creation #4
Description
Following the merge of #3, modular support for adding new Reader subtypes will be available.
This issue is to provide documentation oriented towards developers which describes the process of implementing a new concrete Reader type. Docstrings in the abstract base class give an overview of the roles of the required methods, but additional detail about:
- Argument and return types
- Exceptions that may be raised
- Resource-acquisition behaviour
...amongst other issues should be provided.
This should be accompanied by one or more examples of creating a Reader, testing it, and integrating it with any build, documentation, and CI systems that are present.
