Basic research tree

Just a little drop here to show my current progress in the Research panel. Looks good!

Basic Research tree

I only had to make a small modification on my algorithm to get this working. So so proud of it! This is the first attempt at making one of the 4 research trees. Yes, there will be 4 trees like this one! Zooming in and out is done, as you can see on the image. I still have drag issues when changing the zoom but nothing to worry about.
