Modify insertion sort to sort a list of strings instead of numbers. It shouldn't return anything - it should sort the list "in place". The sorting should ignore case. For example "Zebra" should come after "apple", "maRker" should come after "marble", etc. Name this function string_sort. After calling this function, the list that was passed in should now contain the exact same strings it did before, but in sorted order. The file must be named: string_sort.py
