Number limiting how many items are returned

The limit parameter determines how many top-level items are returned.
For each of these top-level items, the reply_limit parameter determines how many replies to fetch as well.
For example, with a limit of 5, and a reply_limit of 2, we can have a total of 15 items coming back.
This would be 5 top-level items, and 2 replies for each of those items.
