> Returns consecutive sublists of a list, each of the same size (the final list may be
smaller). For example, partitioning a list containing [a, b, c, d, e] with a partition size
of 3 yields [[a, b, c], [d, e]] -- an outer list containing two inner lists of three and two
elements, all in the original order. 
> The outer list is unmodifiable, but reflects the latest state of the source list. The
inner lists are sublist views of the original list, produced on demand using List.subList(int,
int), and are subject to all the usual caveats about modification as explained in that API.
