If the Hash looks like this:

{'en' => {'A' => 1, 'B' => {'C' => 3, 'D' => 'four' }}

I'd like to be able to create a new hash that looks like this (it's for 
a gem that I am trying to write):

{'en' => {'A' => Fixnum, 'B' => {'C' => Fixnum, 'D' => String }}

So I think it should yield the key value pairs when it gets to a leaf, 
but it also seems like I will need more to be able to create the above 
hash.
