Refactoring to be more accurate

I have decided to take this game in a different direction. Currently, the game simulates pseudo-parallel programming, however I want to make it more accurate. So what I have started doing is redirecting the approach to be more accurate to real life. I have started this by having the "source" node be a program that requires X number of threads, and the "target" nodes be variables instead. I still don't know fully where I want to take it past this, but I can feel that there is an interesting game hiding just beneath the surface and I want to explore what interesting things are possible with this simulation.

This change will require heavy refactoring because I will have to switch to a UI-based approach to this game. I have started implementing the user-interaction layer (i.e. managing clicks in script) and once this is working correctly, I will be able to implement the game play stuff I have in mind and once that is done, I will begin experimenting with how I want the main game play loop to work. 

I hope to have an updated version released by the end of this week, at the very latest next week.
