slicing operation. recieves the opSlice!0(x,y) object from x .. y input.
as used with [] brackets, works as slicing with inclusion.
Note: This operation is not natural to the vebtree, as the indicies of keys are not known in general.
However, notably for the case of inclusive slicing (and indeed only working for this kind) one can iterate, e.g.
over all but some indicies from any end of the tree. This method is provided for such iterations.
During preparation, an inclusive slice is created and popFront (according popBack) is called corresponding times,
to remove the approprate number of elements from the front and from the back of the returned range.
