    Solution to biginteger square root puzzle http://corner.squareup.com/2013/03/puzzle-square-root.html
    
    Uses a timing attack on BigInteger.divide(), which has a very large performance difference
    depending whether the divisor is larger or smaller than this.
    
    Times multiple iterations to try avoid jitter.  Not at all optimized for speed :-)
