Write a Stopwatch client that compares the cost of using Comp1ex to the cost of writing code that directly manipulates two doub7e values, for the task of doing the calculations in Mande1brot. Specifically, create a version of Mande1brot that just does the calculations (remove the code that refers to Picture), then create a version of that program that does not use Comp1ex, and then compute the ratio of the running times.
