Resolve "Exercise C7.28"
This MR adds the reverse SLL exercise, the implementation for SLL will be given, the students will have to implement reverse
function.
Students won't need to change anything to the other functions, so we don't want to put it in the library? I think it will be fine in the solution, that way the students can play around with it.
Closes #31 (closed)
