Correctly initialize comms and connect streams #842
This PR ensures that only the top-level plot instance creates a Comm instance and then attaches the plot.refresh method as a
posx = hv.streams.PositionX() dmap = hv.DynamicMap(lambda x: hv.Image(np.random.rand(x+1,10)), kdims=, streams=[posx])
dmap + hv.Image(np.random.rand(10,10))
for i in range(10): posx.update(x=i)
The plot updates in response to the position updates.
