This extension allows the creation of a hierarchical page navigation structure.
It is not intended to structure the contents of a whole wiki like the
Treeview skin. Instead, it is suited to create hierarchical sets of
pages within a web-like wiki.
Possible applications are tutorials and reference manuals.

Introduction:
There are three main forms to organize content on a web site: webs,
sequences and hierarchies.
A web is the most common organization form for a wiki. In this
structure, pages have many free links among them. This format is
well-suited for pages that are loosely related, such as encyclopedic
entries.
In a sequence, pages are organized in a sequential form. One page
leads to the next. This structure is appropriate for tutorials and
presentations.
A more structured form is the hierarchy. It is useful when there is a
natural classification of the content that makes navigation more
intuitive. It could be used, for instance, for a product reference
manual.
MediaWiki excels at the web structure. It can also be used to
represent hierarchies, using internal links and subcategories. But
sometimes it is useful that, in addition to the web structure, the
user is presented with some guidance that will help him to have a
global vision of an information body and to achieve an easier
navigation.
The Hierarchy Extension can be used to create sequential and
hierarchical structures.
