In some cases the wrapper module may not be necessary, but in most cases 
there is a good reason.  A lot of the 'wrapper' modules do a bit more 
work, passing in the necessary Cat structures (i.e. $c->req->params) to 
the external module so you don't have to worry about it.  See for 
example, FormValidator, FillInForm.

In general any form module can benefit from a wrapper that takes care of 
that kind of stuff.  In the case of FormBuilder, I wish there was a 
plugin, because it's not obvious how to integrate it with a Cat app.
