ModuleExtractorclass

Extractor that builds a kind: "module" DocumentationElement from a source file or directory.

• The module's content, description, and title are taken from the source element (MergingExtractor and
  IndexExtractor are expected to have run upstream so .md siblings and README.md are already folded in).
• The module's children are every tree-documentation element found by deep-walking the source — flattened across
  files and subdirectories, but never descending into a tree-documentation's own members.
