Title: add exercise custom set

You can go a lot of different directions with sets in Go, but the string set required here seems a good foundation for doing anything else. I put it just after robot-name because techniques learned here would allow the robot-name bonus to be done easily. If people skipped the bonus, they might go back and do it after this exercise.
