			// create a new controller, using the rotate and func objects created above.  there are 2 overloads to this method.  the one being
			// used uses an internal FrameTimeControllerValue as the source value by default.  The destination value will be the node, which
			// is implemented to simply call Rotate on the specified node along the specified axis.  The function will multiply the given value
			// against the source value, which in this case is the current frame time.  The end result in this demo is that if 50 is specified in the
			// MultiplyControllerValue, then the node will rotate 50 degrees per second.  since the value is scaled by the frame time, the speed
			// of the rotation will be consistent on all machines regardless of CPU speed.
