Chapter 2 Mandelbrot Set wont compile

[Ethan-Arrowood]

I've seen a couple other issues for this section in particular, but I tried compiling the code from the repo as is and I got the following error:

error: could not compile `ch2-mandelbrot`

To learn more, run the command again with --verbose.

I also ran rustup update stable earlier; do I need to be on a different rust version to run this one? From the referenced github issue it states I should add #![feature(exclusive_range_pattern)] to the top of the file and install the nightly build of rust to run it.

Sorry about this @Ethan-Arrowood. I've fixed the problem. Please run git pull and the updated code should compile.
