What's New
Now some apis can get all target items just by one method call.
For example, you can get playlist's all items by follow call
In [1]: r = api.get_playlist_items(playlist_id="PLWz5rJ2EKKc_xXXubDti2eRnIKU0p7wHd", parts=["id", "snippet"], count=None)
In [2]: r.pageInfo
Out[2]: PageInfo(totalResults=73, resultsPerPage=50)
In [3]: len(r.items)
Out[4]: 73
You can see the [README](https://github.com/sns-sdks/python-youtube/blob/master/README.rst) to find which methods support this.
