This branch is the Silver Challenge for Chapter 6. Here we add a UISegmentedControl to our HypnosisView. It has three segments and each changes the colour of our concentric circles. We add the UISegmentedController in BNRHypnosisViewContoller's init method and configure it there. A method changeColor is then implemented that checks the segment touched and accesses the BNRHypnosisView's circle colour property to change it.
