  :body: Returns a basic <em>n</em>-bit checksum of the characters in <em>str</em>, where <em>n</em> is the optional <tt>Fixnum</tt> parameter, defaulting to 16. The result is simply the sum of the binary value of each character in <em>str</em> modulo <tt>2n - 1</tt>. This is not a particularly good checksum.
