Returns the value at the index. get returns nil if index out of
bounds, nth throws an exception unless not-found is supplied. nth
also works for strings, Java arrays, regex Matchers and Lists, and,
in O(n) time, for sequences.
user=> (nth ["a" "b" "c" "d"] 0) "a" user=> (nth ["a" "b" "c" "d"] 1) "b" user=> (nth [] 0 "nothing found") "nothing found" user=> (nth [0 1 2] 77 1337) 1337
