 * @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 the range from start to end should be valid.
