# You write a class called Wrapper, that has a single static function named
# wrap that takes two arguments, a string, and a column number. The function
# returns the string, but with line breaks inserted at just the right places
# to make sure that no line is longer than the column number. You try to break
# lines at word boundaries.
#
# Like a word processor, break the line by replacing the last space in a line
# with a newline.
