This component generates a URL-dependant "URL-trail" -- a list of paths
leading up the current document. 

For example, the URL /foo/bar/baz.html yields the following "Where am I"
string (this is indented and spaced for clarity):

      <a href="/">Home</a>
 &gt; <a href="/foo/">Foo</a>
 &gt; <a href="/foo/bar/">Bar</a>
 &gt; <a href="/foo/bar/baz.html">Baz</a>

which looks (kind of) like (imagine the hyperlinks):

 Home > Foo > Bar > Baz

A functional example can be found at, e.g., http://dir.yahoo.com/Business_and_Economy/Shopping_and_Services/Communication_and_Information_Management/Internet_and_World_Wide_Web/Portals/Personalized/.

Many sites generate these by hand, which gets tedious.

Since it is URL dependent, using informative URL names helps. Some work is
done to make the display string cleaner: the trailing '.html', if any, is
stripped out; underscores are translated to spaces; and it is run through
ucfirst.

TODO

 * Make the individual parts nameable from a configuration file or data
   structure, rather than using the URL.
