$total_pages undefined

[tjjjia]

First of, thank you for sharing the API!

Just ran the examples on my php box; I am getting the following notice with example '1_document'

Notice: Undefined property: Channel::$total_pages in /public/sites/[something]/master/examples/1_document/index.php on line 42

Pagination is broken, and the $per variable also doesn't do much.

The following code also doesn't do much (gets me the above notice as well).

	<?= $channel->total_pages; ?>
	<?= $channel->current_page; ?>

Any idea what is wrong/any idea what I am overlooking?

Looks like the same as my issue ivangreene/arena-js#29
