   Recall that the syntax data[i:j] returns a new list which is a slice of the original list, starting with the element at index i and going up to but not including the element at index j. Behind the scene, that is supported by the __getitem__ method, with the parameter appearing as a special instance of a class named slice.

   However, there is deprecated support, from older versions of Python, allowing you to override the slicing behavior by implementing a special method with signature __getslice__(self, i, j).

   Provide a recursive implementation of __getslice__(self, i, j) for use within the OurList class. Keep in mind that this method should return a new instance of OurList (as opposed to the standard list class). You may assume that integers i and j are nonnegative.

   Remember that the original list should not be mutated when computing a slice, or subseuqently modifying that computed slice.
