//Big Button by Sean Kovacko
//Click the Button on the screen and the color of the 
//background becomes the color the button was. Then the
//button becomes a new color
//Credit to Bruce and Scott who helped me with the idea and code

//This Program is very simple. I became very confused trying to do this project
//and keep having to start new ideas because nothing was working. I had to go to a very 
//basic program idea to focus more on the concepts i was so confused over, and actually 
//figure out how to make it work.

int[] colors = new int[12];
