/* 
* Exercise: Loops and Functions
* As a way to play with functions and loops, implement the square root function using Newton's method.
* To begin with, repeat the calculation 10 times and see how close you get to the answer for various values (1, 2, 3, ...).
* Next, change the loop condition to stop once the value has stopped changing (or only changes by a very small amount).
* See if that's more or fewer than 10 iterations. How close are you to the math.Sqrt?
