View Enable XMOS xTAG 3 in VirtualBox running Linux Mint.md

Just wanted to make a note that I'm running Linux Mint 18.1 (Mate desktop) in VirtualBox with xTIMEcomposer 14.3.0 and I was able to get the xTAG drivers working by simply running the provided driver install script. My Google searches only turned up results like the "Enable USB drivers on Linux" article, which is old. The solution listed there by XMOS does probably work for xTAG 2 devices, however, all of the new xTAG devices from XMOS are not shown in that tutorial, but are included in the new distrobution of xTIMEcomposer. For that reason, and the fact that it's probably just a better idea to use the tools that come with

# This is a demo script I made for myself just to see how Julia's
# syntax for semaphores looks. This script is a basic demonstration
# of a producer and consumer task using a semaphore to protect the
# code sections where the global data variable is accessed.
#
# I built and ran this script with Julia 0.6.0.

Launch PuTTY in UART mode with Raspberry Pi 3 default serial settings. Also set up a realistic text size for PuTTY. By default, it was ultra-tiny on my Linux Mint machine, so we change the font to a normal 12pt font. I figure most people should have the Ubuntu Mono font, so this should work well.
