-# FUNCTION: insertion_sort
-# PURPOSE : Sorts array A, with references to arrays A_i, based on the given
-# key in A_i, address and size of A.
-# INPUTS  : rdi = address for A
-#           rsi = length of A in 64 bit chunks
-#           rdx = index of key to sort by
-# OUTPUTS : rax = address for sorted A
-# CLOBBERS: none
-# NOTES   : Preserves all registers. Recursive psudocode taken from 
-#           https://en.wikipedia.org/wiki/Insertion_sort
