 * @assertion Iterable<E> getRange(int start, int end)
 * ...
 * The provide range, given by start and end, must be valid at the time of the
 * call.
 * A range from start to end is valid if 0 <= start <= end <= len, where len is
 * this list's length. The range starts at start and has length end - start. An
 * empty range (with end == start) is valid.
 * @description Checks that an error is thrown if a range isn't valid.
