+(* You'll propably note that the 'remove' function is missing. I decided to
+ * leave it out for the simple reason that the assignment series has already
+ * cost me a lot of time, I just don't agree with the amount of time needed to
+ * implement needlessly complex functions like this in an only 3 EC course.
+ * Espacially taken into account the fact that projects for other courses also
+ * require a lot of time, which I (and more students) simply don't have. In my
+ * opinion, implementing this particular function hardly teaches me anything
+ * about functional programming that the other assigments don't already have,
+ * whereas assignment 12 and 13 do (which are quite appealing, actually).
+ * Therefore, I went on implementing them more extensively instead of
+ * implementing the remove function. *)
