Subclassing Kwiki::Formatter outside of kwiki

Hi!

I recently uploaded Template::Plugin::KwikiFormat to CPAN. It makes
KwikiFormattingRules usable outside of kiwki (in Template::Toolkit)

This mostly works but as I'm not running a proper kwiki, I have problems
with WikiLinks. WikiLinks are normally converted to a link to the respective
page by looking up the WikiLink somewhere (method html in
Kwiki::Formatter::WikiLink). 

The problem is that this dies with 
  can't locate object method "database_directory" via package "Kwiki::Config
which makes sense, as I didn't configure anything, nor have a proper kwiki
somewhere...

So, I want to override Kwiki::Formatter::WikiLink and
Kwiki::Formatter::TitledWikiLink
but how?

What I want to do is to subclass Kwiki::Formatter, which should use all
classes/methods as usually, besides WikiLink and TitledWikiLink, for which I
want to provide custom classes/methods that do nothing.

All the code samples I found on http://www.kwiki.org seem to only work in a
kwiki context.

So I would really appreciate if somebody could point out to me how to do
this...
