I'm somewhat of a noob at hashes of hashes so I need some help on this one. I have an array of hashes that look like this: 
File Number => [ FirstNum => 1234,
                 NextNum  => 5678,
                 ID       => ID1,
                 File     => text.txt
               ]

I want to transform this into something that would look like: 

1234 => [ NextNum  => 5678,
              ID       => ID1,
              File     => text.txt
        ]

So basically here I wanted to shift the hash so that the first value of the original is now the main value. Hope this makes sense.
