Obstacle Detecting Until Black Line

Modify the Obstacle Detection program you wrote so that it will move safely until the Color Sensor detects a red line on the table, rather than until the robot has traveled certain number of rotations. The obstacle detecting behavior of the program should stay the same. Instead of stopping after the robot has traveled four rotations, program the robot to keep traveling until its Color Sensor detects a black line.
