Contains all text-related classes and modules. This module houses functionality transforming various internal instances to a basic text-based rendering. In most cases, it is not intended to be called explicitly. Its instrumentation will be used automatically by selected instances when calling `render` or `to_text`/`to_headers`.
This is also the place where additional supported instance types should be added. Please, refer to internal documentation for details on how to add a new instance type.
