 With `cxListClone()` you can create deep copies of the elements in a list and insert them into another list.

 The function `cxListDifference()` is similar to `cxListClone()`,
-except that it only clones elements from the minuend that are _not_ contained in the subtrahend.
-It is optimized for sorted lists, in which case it will take linear time instead of quadratic time for the operation.
