Here is version 2 of the ray tracing algorithm. I'm testing it out in both the x and y directions. It needs to be able to extrapolate properly. I will double check the math with you guys. This will remain a branch until it's 100% working
Updated README
Version 2 is complete. This update comes with a more convenient demonstration. To use: Make a random circle. Click once in the box below the
button. Click again and a ray will be made. Move the mouse to move the ray.
