Displays a vastly condensed hierarchial list of pages, which is especially valuable for large sites which can run to hundreds of pages.

Always displays the current page, the pages above it back to the home page, and the current page's children.

The behavior of the widget is all configurable through its configuration screen, as follows:

* The title is optional (blank will emit no heading)
* Pages may be sorted in Menu Order or  alphabetically.
* Siblings to the current page, if enabled, means that child 
pages of the current page’s parent will be displayed. 
Disabling this makes for shorter page lists but the user
might not be able to move “sideways” in the site.
* If there are many top-level pages (pages with no Parent set),
you can disable their listing.
* If your site has an Introduction or splash page,
as a static home page, you might want to disable showing it
(presumably it is accessible through an icon link).
However, if the homepage has children, it will always be displayed
(otherwise you could never navigate to those pages).
