     * Gets a sublist of a list, truncated at the end of the list if too many elements are selected.
     * This behaves exactly like List.subList, including all notes in its Javadoc concerning
     * structural modification of the backing List, etc. with one difference: if the end index is
     * beyond the end of the list, instead of throwing an exception, the sublist simply stops at the
     * end of the list.  After the fifth or so time writing this idiom, it seems worth having a
     * function for. :-)
