<div class="block">A scanner that instantiates iterators on the client side instead of on the tablet server. This
can be useful for testing iterators or in cases where you don't want iterators affecting the
performance of tablet servers.
<p>
Suggested usage:
<pre>
<code>
Scanner scanner = connector.createScanner(tableName, authorizations);
scanner = new ClientSideIteratorScanner(scanner);
</code>
</pre>
<p>
Iterators added to this scanner will be run in the client JVM. Separate scan iterators can be run
on the server side and client side by adding iterators to the source scanner (which will execute
server side) and to the client side scanner (which will execute client side).</div>
