Preprocessors are run after the text is broken into lines. Each preprocessor implements a `run` method that takes a pointer to a list of lines of the document, modifies it as necessary and returns either the same pointer or a pointer to a new list. Preprocessors must extend `Preprocessor`. cy)z Each subclass of `Preprocessor` should override the `run` method, which takes the document as a list of strings split by newlines and returns the (possibly modified) list of lines.
