=head1 DESCRIPTION

This router module reblesses a Kelp application into its own controller class.
This allows you to structure your web application in a classic object oriented
fashion, having C<$self> an instance to the current class rather than the main
web application.

You must create a main I<controller> class which inherits from Kelp.  Each
subsequent class can inherit from this class, taking advantage of any common
functionality.
