When an MKDoc document has child documents, the titles of those child documents are magically linked within the text of the parent document.
This is a very useful feature, but it should be configurable to increase the range of covered documents:
The default range should be increased to include the parent of the current document by default
Optionally siblings can be magically hyperlinked
Optionally uncle/aunt documents can be magically hyperlinked
This would make an MKDoc document much more similar to a wiki document, something else we can do to make MKDoc more wiki-like would be to automatically link to any document on the site when the text [[has double-brackets]] like so.
