/* The reason I created this was two-fold.  1. To learn Java 2. To learn about numerical analysis and numerical methods of arithmetic. 
This code shows that the Babylonian Method of computing square roots is as accurate as the Java numerical method using sqrt() after as few
as 10 iterations for numbers within the limits of a double.  I'm certain that it can be improved (and I have no vanity of authorship i.e., I welcome
criticism  [email protected]).  I love learning and sharing what I find, if you have some math-related code you're itching to share please
let me know!

There are numerous methods for computing square roots (http://en.wikipedia.org/wiki/Methods_of_computing_square_roots). 
"The basic idea is that if x is an overestimate to the square root of a non-negative real number S then S/x will be an underestimate and so the average 
of these two numbers may reasonably be expected to provide a better approximation."
