Wall Avoidance Sketch - Small Change

I made a small change to the “Wall Avoidance” example sketch (Wall_Avoidance.ino) to center the ultrasonic range finder servo on start-up. You may also want to make this same change to the “Ultrasonic_Range_Finder.ino” parts sketch.

Old
void setup() 
{
}
======================
New
void setup() {
  sparki.servo(SERVO_CENTER); // Center the Servo (jjd 20140219)
}

Note: Be sure to hold the flashlight very close to the sensors to have Sparki follow it.
