A Parallel Mandelbrot Set Plotter

This program plots the Mandelbrot set and writes it out as a PNG file. It uses Rust's concurrency primitives to distribute the work across eight threads.

This example is the multi-threaded version based on the Rayon crate in the "Concurrency" chapter of the Programming Rust Book.

It uses the Rayon library. Rayon provides a parallel iterator API that makes the code much simpler. It looks a lot like Rust code that uses plain old iterators.
