 =====Background=====
 For this project, you will be working with a C program using the wiringPi library on the Raspberry Pi, wiring up a circuit containing an RGB LED to your breadboard and witnessing your ability to access and control it in varying states of on and off (more than just simply "ON" and "OFF") via a software-based Pulse Width Modulation (PWM) scheme.
