> Minor addition to assist new users with a GroupByKey example in Java. Specifically:
> Add the following content to provide a Java example at the end of section 4.2.2. GroupByKey.
> ------------------
> Using {{GroupByKey}} is straightforward:
> {\{< highlight java >}}
> // The input PCollection.
> PCollection<KV<String, String>> mapped = ...;
> // Apply GroupByKey to the PCollection mapped.
> // Save the result as the PCollection reduced.
> PCollection<KV<String, Iterable>> reduced =
> mapped.apply(GroupByKey.<String, String>create());
> {\{< /highlight >}}
