'''
A connection which attaches to a particular named session on the server.
Always call either pull() or push() immediately after creating the session
(until these are called session.document will be None).
The bokeh.client.push_session() and bokeh.client.pull_session() functions
will construct a ClientSession and push or pull in one step, so they are
a good way to obtain a ClientSession.
Args:
session_id (str) :
The name of the session or None to generate one
websocket_url (str) :
Websocket URL to connect to
io_loop (``tornado.ioloop.IOLoop``, optional) :
The IOLoop to use for the websocket
