 It provides you with a generic new() for component construction through Catalyst's
 component loader with config() support and a process() method placeholder.
 
+B<Note> that calling C<< $self->config >> inside a component is strongly
+not recommended - the correctly merged config should have already been
+passed to the constructor and stored in attributes - accessing

+wrong values (as it only holds the class wide config, not things loaded
