Unity OpenCVSharp Camshift

I've seen lots of Youtube videos with people demonstrating using openCV with Unity, but haven't found many that include demo source code to actually play around and learn.

So I wrote my own Unity demo based on shimat's openCVSharp wrapper for openCV. In the demo, the user can select a region of interest to track via openCV's CAMshift algorithm.

The code is open sourced. I'm hoping people can use it to learn openCV for Unity and maybe even suggest improvements in my implementation.
