Tool Suggestion: Projector Simulator

It is difficult to develop or debug effects without a projector. MusicBeam uses the light beams from a projector to make effects. Developers must imagine how the beams look like when developing without a projector.

I created a tool that takes the image that is intended to go to the projector (second window) and creates a light beam simulation for it. Developers can pan, rotate, and move around a virtual room to see their effects in motion.


Code to be added to Stage class:
```Java
ProjectorSim sim = new ProjectorSim();
String[] args = {"Simulator"};
PApplet.runSketch(args, sim);

draw(){
...
sim.updateImage(get());
...
}

```

Developers do not need to add any additional code to their effects class. This tool allows for quick prototyping and debugging.
