I’ll do a much more thorough post when the project is further along. For those playing along at home, you can see that I’ve totally re-written the code for this new version. So far, it has much less functionality but much more stability and flexibility.
Hey! This post was written a long time ago, but I'm leaving it up on the off-chance it may help someone. Proceed with caution. It may not be a good idea to blindly integrate this code or work into your project, but instead use it as a starting point.
