# contract: writeSquares: number string -> void
# purpose: write the first <howMany> squares (starting
#          with 1 squared) into a file <whereToPutThem>
#          NOTE: if <whereToPutThem> currently exists
#          when this is called, ITS PREVIOUS CONTENTS WILL
#          BE DELETED
# example: if I call writeSquares(5, "looky.txt"), then
#          looky.txt will contain (ignoring the comment marks)

#25
