Write a function stroverlap that takes (at least) two strings, and concatenates them, but does not duplicate any overlap. You only need to worry about overlaps between the end of the first string and the beginning of the second string. Examples: batman, manonthemoon = batmanonthemoon batmmamaman, mamamanonthemoon = batmmamamanonthemoon bat, man = batman batman, batman = batman batman, menonthemoon = batmanmenonthemoon
