    Nitpick - no need for this if check I think.

> Add a new example to the geode-examples that demonstrates partitioning.
> The example will use the same structure as the replicated example, starting 2 servers
that host a partitioned region (with no redundant copies).  Run the producer to populate the
region.  Run the consumer to see the contents of the region. Then, stop one of the servers
and run the consumer again to notice that only roughly half (with 2 servers and hopefully
a reasonable hash) of the entries are present.
