I'd like to have a simple definition of the meanings of 'type' and 'data' 
and maybe a clarifing example on their use.

I've read the Zipper doc on he wiki ,but I can't make it work on n-ary 
trees,and most of all they are not any clear the performance hits on using 
more complex 'data'

						Thanks Paolino
