Subject: Flatten out Hash

Hi,

I would like to take a nested hash that looks like this:

{"a"=>{"b"=>{"c"=>1}, "b2"=>{"c2"=>2}}}

and turn it into an array of 2 element arrays like this:

[["a: b2: c2: ", 2], ["a: b: c: ", 1]]

Is there a simple way to do this?  I wrote a method that iterates
through the nested hashes recursively, but it's a bit cumbersome.
