This is a conceptual data structure problem. I would love to hear the answers if anyone has any ideas.

You have an array of arrays, turn it into a single hash of hashes where the final element of each array is the value and each previous element in order are the keys to get to that value.

Desired effect Example:
IN: Array of Arrays:
(0=>(a,b,e,d), 1=>(a,b,c,f), 2=>(d,h,f), 3=>(d,i,g))
OUT: Hash:
$out{a}{b}{e} = d
$out{a}{b}{c} = f
$out{d}{h} = f
$out{d}{i} = g
