For backward compatibility reasons grokcore.formlib both uses
zope.formlib, and is designed around the structure of zope.formlib.
That gives the new user two different software models fo formlib. I
still have not figured them out. All I know is that I am not allowed to
subclass the render method. Very frustrating. Best if there were just one grok formlib library. Much less confusing.
